Ἰησοῦς

An angel speaks to a frightened carpenter in a dream. The carpenter has discovered that his fiancée is pregnant; he has been planning to dismiss her quietly to spare her public shame; he has not yet decided what to do when the angel arrives in the night. The angel tells Joseph that the child Mary carries is from the Holy Spirit, that the child must be received, that the child will save His people from their sins.

And the angel tells Joseph what to name the child.

“She will give birth to a son and you will name him Jesus because he will save his people from their sins.” (Matthew 1:21, NET)

The name comes with its own explanation. you will name him Jesus — the personal name, the name a Jewish boy would carry through Galilee. For he will save his people from their sins — the reason. The two halves of the verse interpret each other. The name IS the mission. The name IS the announcement of what the child has come to do.

This is what the Greek New Testament knows that English Bible readers often miss. In Greek the name is Iēsous. Iēsous is the Septuagint’s transliteration of the Hebrew Yeshua, which is itself a shortened form of Yehoshua — the name we know in English as Joshua. And Yehoshua is a compound of two Hebrew elements: Yeho- (a shortened form of YHWH, the personal divine name) and -shua (from yasha’, the verb meaning “to save” or “to deliver”). Put the parts together and the name means YHWH saves — or, with slight variation, YHWH is salvation.

The name itself is a creed. To say His name is to confess that the LORD saves through this Person. Matthew’s etymological gloss in 1:21 is not exegetical decoration; it is the announcement of the gospel in the form of a baby’s name. The carpenter and his wife are told to name the child what the child is: YHWH saves.

The related entry on Logos explores the Word made flesh. Other entries consider, from several angles, who He is: theos and patēr and hyios, anthrōpos and theotēs and prōtotokos and archē. This entry names Him by the name He was given at His circumcision, the name His mother used, the name His Father exalted above every name.

This entry is about that word.

The Word

The Greek word is Ἰησοῦς (Iēsous), pronounced in the Erasmian convention as ee-AY-soos, with the accent on the second syllable. The word is a proper name, declined like other masculine nouns of the first declension that end in -ous: nominative Iēsous, genitive Iēsou, dative Iēsou, accusative Iēsoun, vocative Iēsou. In running Greek prose the name appears in all five forms, depending on its grammatical function in the sentence.

Iēsous is not natively Greek. It is the Septuagint’s standard transliteration of the Hebrew name Yehoshua and its shortened later form Yeshua. When the LXX translators encountered the name in the Hebrew Old Testament — most prominently as the name of Moses’s successor, the one English Bibles call Joshua — they rendered it Iēsous. The same convention carries into the New Testament. When the Greek New Testament calls the Lord Iēsous, it is using the Greek form of the Hebrew name Yeshua. When Hebrews 4:8 mentions Iēsous in reference to the leader who brought Israel into Canaan, it is using the same form for Yehoshua / Joshua. The two Old Testament and New Testament figures share a name — in Greek, the very same name; in Hebrew, the same name with minor orthographic variation.

The etymology of the Hebrew name is well established. Yehoshua is a compound of two elements:

Yeho- — a contracted form of the divine name YHWH. This shortened form appears as the first element in many Hebrew names — Yehonathan (Jonathan, “YHWH has given”), Yehoshaphat (Jehoshaphat, “YHWH has judged”), Yehoyada (Jehoiada, “YHWH knows”), Yehoyaqim (Jehoiakim, “YHWH establishes”), and so on. In each case the Yeho- element brings the divine name into the personal name as part of a theological statement about the bearer.

-shua — derived from the verb yasha’, “to save,” “to deliver,” “to rescue.” The same Hebrew root produces the noun yeshu’ah (salvation) and the name Yesha’yahu (Isaiah, “YHWH saves” — a closely related name with the elements in reverse order).

Combined, the name Yehoshua means YHWH saves or YHWH is salvation. The short form Yeshua — which is the form actually used in the late Second Temple period and which lies behind the Greek Iēsous — keeps the same meaning. The name was common among first-century Jews precisely because of its theological depth and its association with the figure of Joshua. According to historical estimates, Yeshua was among the most common male Jewish names of the period — perhaps the fourth or fifth most common name overall.

The word family in Greek is sparse because Iēsous functions primarily as a proper name. The most theologically important related term is the Greek verb sōzō (to save), explored in Sozo. Every time the New Testament says sōzō, the family connection to Iēsous is present, even when the name itself does not appear in the verse.

Compound names involving Iēsous are rare in the New Testament but not unknown. Acts 13:6 mentions Bar-Iēsous — “Son of Jesus” — the magician Paul encounters in Paphos. The name was common enough that the Aramaic compound was unremarkable; it tells us nothing about the magician’s relation to the Lord.

The LXX background — Iēsous as the Greek for Joshua — has theological consequences the New Testament occasionally exploits. The most striking instance is Hebrews 4:8: “For if Joshua had given them rest, God would not have spoken afterward about another day.” The English reader sees “Joshua” in this verse (most translations supply the name to avoid confusion); the Greek reader sees Iēsous. The author of Hebrews is making a pointed contrast: Yehoshua the son of Nun did not give Israel the final rest; the true Iēsous, the One in whom YHWH’s saving promise comes to full expression, gives the rest that lasts. The shared name is the typological key.

Range of Meaning

Iēsous in the New Testament covers a relatively narrow range, because it functions primarily as a proper name. The major uses:

The personal name of Jesus of Nazareth. The dominant use, occurring nine hundred and seventeen times in the New Testament. The name is used by itself, in combination with titles (Iēsous Christos, Iēsous ho Christos, Iēsous ho Nazōraios), and with various geographical or familial identifiers (Iēsous ho apo Nazaret, Iēsous ho huios Iōsēph).

Joshua, the Old Testament figure. Used at Acts 7:45 (Stephen’s speech, recalling Israel’s entry into Canaan “with Iēsous”) and at Hebrews 4:8 (the Joshua/Jesus typology noted above).

Jesus called Justus. A minor character in Paul’s letters. Colossians 4:11 mentions “Jesus who is called Justus” among Paul’s coworkers, identified separately to avoid confusion with the Lord.

Bar-Jesus the magician. Acts 13:6. The Cyprian magician opposed by Paul on his first missionary journey. The Aramaic patronymic places his father in the same naming tradition.

Other ancient Jews named Jesus. Outside the New Testament, the historian Josephus mentions several first-century Jews named Iēsous, including a high priest and several minor figures. The name was common; the particular Iēsous who is the subject of the gospels is identified by His distinctive titles and by His miraculous works.

The dominant theological weight of the name in the New Testament is the first sense. When the New Testament says Iēsous, it almost always means the Lord — the Iēsous who was born in Bethlehem, lived in Galilee, taught in parables, died on a cross outside Jerusalem, rose on the third day, and ascended to the right hand of the Father. The other uses are present but minor.

Where You’ll Meet It

Matthew 1:21. “She will give birth to a son and you will name him Jesus because he will save his people from their sins.” The angelic announcement to Joseph in his dream. The Greek: kaleseis to onoma autou Iēsoun, autos gar sōsei ton laon autou apo tōn hamartiōn autōn. The verse explicitly etymologizes the name: Iēsous is given because He will save (sōsei) His people. The Greek verb sōsei is the future of sōzō, the Greek word that translates the Hebrew yasha’ in the LXX. The name and the explanation share the same Hebrew root.

This is the entry’s keystone verse. Matthew preserves the etymological connection that Greek readers without Hebrew would otherwise miss. The Evangelist is telling us, in effect, the name is the gospel. The child is given a name that means “YHWH saves,” for the reason that He will save His people from their sins. The name names the mission, and the mission names the Person.

Luke 1:31. “Listen: You will become pregnant and give birth to a son, and you will name him Jesus.” The parallel angelic announcement to Mary. Luke does not include the etymological gloss; the name is simply given. But the structural parallel with Matthew is significant: both gospels record that the child’s name was given by divine instruction, not chosen by the parents. The naming of Jesus is not a parental preference; it is a divine appointment.

This matters theologically. The name Iēsous was not selected by Joseph or Mary. They received it from the angel. The name itself is part of the gift of God in the incarnation — the name and the Person come together as one divine appointment.

Philippians 2:9-11. “As a result God highly exalted him and gave him the name that is above every name, so that at the name of Jesus every knee will bow —in heaven and on earth and under the earth— and every tongue confess that Jesus Christ is Lord to the glory of God the Father.” The climactic moment of the Philippian Christological hymn.

The Greek is dense and worth parsing. Hyperypsōsen — “highly exalted,” a double-compound verb that combines hyper- (above, beyond) with the verb hypsoō (to lift up). The Father has exalted the Son above-beyond-up — the verb piles up its prefixes to express the maximal nature of the exaltation. Echarisato autō to onoma to hyper pan onoma — “gave him the name that is above every name.” The verb charizomai means “to give as gift” — God’s exaltation of the Son is gift, not earned reward (though the hymn has just narrated the Son’s obedience). Hina en tō onomati Iēsou pan gony kampsē — “so that at the name of Jesus every knee will bow”

The hymn is doing two things at once. First, it is identifying the “the name that is above every name” with the name Iēsous — the very name the angel gave the child in Matthew 1:21. The personal human name of the man from Nazareth is the name now exalted above every name in the universe. Second, the hymn is connecting this name to the universal confession that “Jesus Christ is Lord” (kyrios Iēsous Christos) — using the divine title kyrios that the LXX uses for YHWH. The exaltation of the name Jesus is the exaltation of the One who, the angel said, would save His people from their sins.

Acts 4:12. “And there is salvation in no one else, for there is no other name under heaven given among people by which we must be saved.” Peter’s defense before the Sanhedrin. The Greek: ouk estin en allō oudeni hē sōtēria, oude gar onoma estin heteron hypo ton ouranon to dedomenon en anthrōpois en hō dei sōthēnai hēmas. Two uses of sōtēria / sōthēnai (salvation / to be saved) bracket the verse: there is no other salvation, no other name. The name and the salvation are inseparable.

The verse is exclusive in its claim. The salvation that Iēsous names is not one path among many. It is the only path, because it is the path the Father has provided. Peter is not making a philosophical argument; he is testifying to what God has done through this name. The salvation has been given in this Person, with this name, and the Sanhedrin cannot dismiss it without dismissing what God has accomplished.

Hebrews 4:8. “For if Joshua had given them rest, God would not have spoken afterward about another day.” The Greek: ei gar autous Iēsous katepausen, ouk an peri allēs elalei meta tauta hēmeras. The English translation (most modern versions) supplies “Joshua” rather than “Jesus” to clarify the reference, but the Greek uses the same name in both Testaments. The author of Hebrews is exploiting the dual reference. Yehoshua the son of Nun gave Israel a rest in the promised land — but not the ultimate rest. The true Iēsous — the Lord Jesus — gives the eternal rest that the earthly conquest only foreshadowed.

The typology is precise. Joshua is a type of Jesus (the typos / antitype structure of Hebrews 11:19 and elsewhere). Both have the same name in Greek; both lead God’s people into rest; but the rest Joshua gave was provisional, while the rest Jesus gives is final. The shared name is the linguistic flag that the typological connection is intended.

What Confessional Lutherans Hear

Three things here deserve drawing out.

The name is the gospel in miniature. Matthew 1:21’s explicit etymology — “she will give birth to a son and you will name him Jesus because he will save his people from their sins.” — collapses the name and the mission into one. Every time we say His name we confess that YHWH saves through this Person. The Hebrew etymology is not optional information for theological enrichment; it is the meaning of the name itself. The angel did not just tell Joseph what to call the baby; the angel told Joseph what the baby was for.

This emphasis has practical consequences. The Christian who says “Jesus” in prayer or confession is uttering a one-word creed. The name itself confesses what the Person does. The Lutheran liturgical tradition’s frequent invocation of the name — at baptism, at the Lord’s Supper, at the dismissal — is not formal repetition; it is the church’s confession of the saving God, named precisely.

The name was given, not chosen. Both Matthew 1:21 and Luke 1:31 record that the name was given by angelic instruction, not selected by Joseph or Mary. This signals that the salvation in Jesus is God’s initiative, not human invention. The parents did not choose what to call the child; God told them what He had named His Son. The naming is part of the gift of the incarnation.

This emphasis matters against various forms of “I discovered God / I found Jesus / I invited Christ into my life” piety that center on the believer’s initiative. The Lutheran tradition has consistently insisted on the priority of divine action. Coram Deo, the believer does not choose Christ; Christ chooses the believer. The naming of Jesus is one of the structural markers of this divine priority. God names His own Son before the world has a chance to invent a name for Him.

The name above every name. Philippians 2:9-11. The personal human name of the man from Nazareth has been exalted by the Father above every name. The name common in first-century Galilee has become, by divine exaltation, the name at which every knee in heaven and earth will bow. The historical Jesus and the cosmic Lord are not two figures wearing the same costume; they are the same Person, named with the same name, in His earthly humility and His exalted glory.

This emphasis grounds the Lutheran confidence in the unity of Christ. The Jesus who suffered is the Jesus who reigns. The name that was mocked at the cross is the name above every name. There is no division between the humble Galilean and the exalted Lord; they are the same Person, named with the same name throughout. The Philippian hymn moves from the kenosis (the emptying, the obedience to death) to the exaltation (the name above every name), and the same Iēsous is the subject of both halves.

The pastoral payoff is substantial.

When you pray in Jesus’s name, you are not appending a magical formula to the end of your petitions. You are praying as one who belongs to the name God has exalted — invoking the One in whom the Father has gathered all His saving purposes. The prayer is heard because the Father has exalted this name.

When you confess Jesus Christ is Lord, you are joining the universal confession that the Philippian hymn predicts will eventually be made by every tongue. The confession is yours now, in faith; it will be universal then, at the end. The believer’s present confession anticipates the cosmic conclusion.

When you are baptized, you are baptized into the name (Matthew 28:19 — eis to onoma). The Trinitarian formula at baptism — Father, Son, and Holy Spirit — incorporates you into the name God has revealed. The Christian’s identity is in the name. The Christian’s salvation is in the name. The Christian’s confession is in the name.

Where People Get It Wrong

The “magical name” reduction. Some streams of contemporary Christianity treat the name of Jesus as a verbal talisman — invoke it in prayer to get what you want; command demons in it; deploy it as a spiritual weapon. The New Testament does sometimes describe miraculous events in connection with the name (Acts 3:6, 16:18, etc.), but the name is not separable from the Person. To call on the name of Jesus is to call on Jesus Himself. To pray in His name is to pray as one who belongs to Him. The name has power because the Person has power, not because the syllables themselves are magical. Acts 19:13-16 illustrates the danger of treating the name as a formula apart from faith in the Person — the seven sons of Sceva tried to use the name of Jesus as a verbal exorcism technique and were physically driven from the house.

The “name as private password” reduction. Some American evangelical preaching treats “praying in Jesus’s name” as a procedural requirement — you have to say the words at the end of the prayer for it to count. The New Testament meaning is broader. To pray in His name is to pray as one who belongs to Him, in His authority, according to His will, with His mediation. The closing formula “in Jesus’s name, amen” is fine and faithful as a way of articulating this, but the saying of the words is not the substance. The substance is the believer’s union with Christ and the Father’s reception of the prayer through Christ’s ongoing mediation.

The Acts 4:12 softening toward universalism. Some recent theology has tried to soften the exclusivity of Acts 4:12 (“no other name under heaven”) by reading “the name” as a principle or a representation rather than the actual personal name of Jesus. On this reading, those who do not name Jesus may still be saved if they are devoted to the same saving principle by other names. The New Testament will not bear this. Peter is not articulating a principle; he is testifying to what God has done through this specific Person. Confessional Lutherans hold the exclusivity of Acts 4:12 with full seriousness, while recognizing that the eternal destiny of those who never heard the name is a question Scripture leaves more open than some theologies have wanted to claim.

The “Yeshua” recovery movement overcorrection. Some Messianic Jewish movements and some pop-religious enthusiasts insist that Christians should call the Lord “Yeshua” rather than “Jesus” because the Hebrew is more authentic. The argument has appeal but rests on a faulty premise. The Greek New Testament — the document the church inherited as Scripture — calls Him Iēsous. The English “Jesus” comes through the Greek to Latin (Iesus) to English (Jesus). Calling Him “Jesus” is faithful to the apostolic naming, not a corruption of it. The Greek transliteration is itself part of how the gospel was given to the nations. The same God who chose the Hebrew name Yeshua for the child preserved the Greek name Iēsous in the apostolic Scriptures. “Yeshua” is fine; “Jesus” is fine; “Iēsous” is fine; the church has called Him each in its various contexts.

The reduction of the name to historical reference. Some critical scholarship treats “Jesus” as merely the personal name of the historical man, with all the divine and theological weight added by the church later through what is sometimes called the “Christ of faith” overlay. The New Testament will not bear this reduction. The name itself was given with theological content from the beginning — “she will give birth to a son and you will name him Jesus because he will save his people from their sins.” (Matthew 1:21, NET). The mission is named with the name. The “Jesus of history” and the “Christ of faith” distinction collapses at the point of the angelic naming: this Jesus is from the start the one who saves; the historical figure and the theological figure are the same Person with the same name.

The reduction of the Philippian hymn to liturgical convention. Some Bible study leaders treat Philippians 2:9-11 as an early Christian hymn that the church has inherited as a beautiful piece of liturgy but that lacks specific theological substance. The hymn is theologically substantial. It claims that the personal name of Jesus has been exalted above every name — including every other divine name, every angelic name, every name borne by any spiritual or political power in heaven or on earth. It claims that every knee will bow at the name. It claims that every tongue will confess kyrios of this Iēsous — using the Septuagint’s translation of YHWH. The hymn is not decorative; it is one of the most pointed Christological assertions in the New Testament.

So What

The Sunday school teacher angle is direct: teach the Hebrew background of Jesus’s name. Most Christians have heard “Jesus means Savior” without seeing the full picture. The Hebrew is Yeshua, the longer form Yehoshua, combining Yeho- (a contracted form of YHWH) and -shua (from yasha’, “to save”): YHWH saves. The same name is Joshua in the Old Testament and Jesus in the New — the Greek uses one form, Iēsous, for both, and Hebrews 4:8 plays on the dual reference: Yehoshua son of Nun could not give Israel the final rest; Iēsous the Lord does. Matthew 1:21 closes the loop: “She will give birth to a son and you will name him Jesus because he will save his people from their sins.” The name and the mission are one root. Every time we say His name, we confess the gospel.

For Bible study leaders, the application extends to the Philippian hymn (Philippians 2:5-11). The “As a result God highly exalted him and gave him the name that is above every name, so that at the name of Jesus every knee will bow —in heaven and on earth and under the earth— and every tongue confess that Jesus Christ is Lord to the glory of God the Father.” climax of verses 9-11 deserves unpacking: the verbs hyperypsōsen (highly exalted) and echarisato (gave as gift); the universal scope (every knee, every tongue); the confession kyrios Iēsous Christos, using the same kyrios the Septuagint uses for YHWH. It is a one-paragraph Christology the church has been working out for two millennia.

For pastoral application, the name shapes the believer’s whole life. You are baptized in the name — the Trinitarian formula incorporates you into the name God has given. You pray in the name — every prayer is offered through Jesus, whose ongoing intercession (Hebrews 7:25) makes it acceptable. You confess the name — the Christian’s testimony is not first about his own experience but about the One he confesses: Jesus Christ is Lord.¹ And you die in the name — the last breath is the same name the first breath was baptized into.

These titles of Christ converge on the name that encompasses them. Matthew 1:21 also directs us to the doctrine of sin: He saved His people from their sins. To understand what He saved them from, see the related entries on Kosmos, Thanatos, Anomia, Paraptoma, and Planao. Christology answers Who is the Savior? The doctrine of sin answers What did He save us from?
