In Hebrew the divine self designation begins with אֶהְיֶה אֲשֶׁר אֶהְיֶה, transliterated Ehyeh Asher Ehyeh, from the verb היה hayah meaning to be or to come to pass, expressing self existent covenant being, the God who is and who will be faithful in action, which in the Berean Literal Bible is rendered “I AM WHO I AM” ~Exodus 3:14.
Flowing from this is the tetragrammaton יהוה, transliterated YHWH, likely vocalized as Yahweh, the third person form related to the same verbal root, meaning He Is or He Causes To Be, the covenant name revealed to Israel, invoked in worship, bound to redemption, mercy, judgment, and oath faithfulness throughout the Hebrew Scriptures.
The salvific name that carries this covenant identity into personal form is יְהוֹשֻׁעַ Yehoshua, meaning YHWH saves, later shortened in post exilic usage to יֵשׁוּעַ Yeshua, both names directly embedding the divine name within the act of salvation, signaling that deliverance belongs to YHWH alone.
In Greek the Hebrew Yeshua is transliterated as Ἰησοῦς Iēsous, the form used consistently in the Septuagint and the New Testament, not as a reinterpretation but as a phonetic rendering that carries the same theological weight, namely that YHWH saves, now revealed in the person and work of Jesus of Nazareth.
The Greek Scriptures also identify Jesus with the divine name through the title Κύριος Kyrios, Lord, the established Septuagint substitute for YHWH, so when the New Testament confesses “Jesus Christ is Lord” ~Philippians 2:11, it is affirming that the covenant name revealed in Hebrew Scripture is rightly confessed in and through Jesus.
Thus the movement is not from one god to another nor from one meaning to a lesser one, but from revelation to incarnation, from Ehyeh Asher Ehyeh to YHWH, from YHWH saves to Yeshua, and from Yeshua to Iēsous, with the crucified and risen Christ bearing the full identity, authority, and saving power of the covenant God.
