YHWH (יהוה)

“God said to Moses, ‘I AM WHO I AM.’ And he said, ‘Say this to the people of Israel: I AM has sent me to you.’” — Exodus 3:14

YHWH is the personal, covenant name of God — the most sacred name in all of Scripture. It appears over 6,800 times in the Old Testament. The four Hebrew consonants (yod-he-vav-he) are known as the Tetragrammaton.

Meaning

The name is derived from the Hebrew verb hayah (הָיָה), “to be.” It communicates God’s:

• Self-existence — He depends on nothing outside Himself for His being
• Eternality — He is the same yesterday, today, and forever
• Covenant faithfulness — “I AM” implies ongoing, active presence with His people

The Name Revealed

God revealed this name to Moses at the burning bush (Exodus 3:1–15) in the context of delivering Israel from Egypt. When Moses asked for God’s name, the answer came in a form that resists reduction to a mere label: ehyeh asher ehyeh (אֶהְיֶה אֲשֶׁר אֶהְיֶה) — “I AM WHO I AM” or “I WILL BE WHAT I WILL BE.” The ambiguity is deliberate: God’s name is not a definition that the creature can master but a promise of presence — He will be known by what He does (Exodus 6:6–7). YHWH is thus the name most closely associated with God’s redemptive acts — His saving power demonstrated in history.

Later, at Sinai, YHWH passed before Moses and proclaimed His own character in what has been called the most quoted passage within the Old Testament itself: “YHWH, YHWH, a God merciful and gracious, slow to anger, and abounding in steadfast love — hesed (חֶסֶד) — and faithfulness — emet (אֱמֶת)” (Exodus 34:6–7; cf. Numbers 14:18; Nehemiah 9:17; Psalm 86:15; 103:8; Joel 2:13; Jonah 4:2). This self-declaration reveals that the name YHWH is not abstract metaphysics but covenant identity — the God who binds Himself to His people in mercy, faithfulness, and love.

The Pronunciation Question

The original pronunciation of the Tetragrammaton is uncertain. Ancient Hebrew was written without vowels, and by the Second Temple period, Jewish tradition had ceased pronouncing the name aloud out of reverence for the commandment, “You shall not take the name of the LORD your God in vain” (Exodus 20:7). When reading Scripture, Jews substituted Adonai (“Lord”) or HaShem (“the Name”) in place of YHWH.

The form Jehovah arose in the medieval period when scribes combined the consonants YHWH with the vowel markings from Adonai, producing a hybrid form never intended as a real pronunciation. Most modern scholars favor Yahweh as closer to the original, based on early Greek transcriptions (such as Clement of Alexandria’s Iaoue) and the shortened forms Yah (as in “Hallelujah,” Psalm 68:4) and Yahu found in Hebrew names like Elijah (Eliyahu).

The Tetragrammaton in the Septuagint

When Jewish scholars translated the Hebrew Scriptures into Greek (the Septuagint, or LXX), they rendered YHWH as kyrios (κύριος) — “Lord, master, sovereign.” This translation choice had enormous theological consequences: when the New Testament writers called Jesus kyrios, they were placing Him in the very position occupied by YHWH in the Old Testament. The confession kyrios Iēsous (κύριος Ἰησοῦς) — “Jesus is Lord” (Romans 10:9; 1 Corinthians 12:3; Philippians 2:11) — is therefore not merely an acknowledgment of authority but a declaration that the crucified and risen Jesus bears the divine name itself.

“Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow.” — Philippians 2:9-10

YHWH in the New Testament

Jesus made stunning claims using the ego eimi (ἐγώ εἰμί, “I am”) formula in the Gospel of John, identifying Himself with the God who spoke to Moses:

• “Before Abraham was, I am” (John 8:58) — a direct invocation of the divine name, prompting the crowd to take up stones
• “Unless you believe that I am he, you will die in your sins” (John 8:24) — linking salvation to recognizing His divine identity
• “I am the bread of life” (John 6:35), “I am the light of the world” (John 8:12), “I am the resurrection and the life” (John 11:25) — each ego eimi statement reveals a facet of what it means that God is present with His people

The early Church consistently applied Old Testament YHWH texts to Jesus. Paul quotes Isaiah 45:23 — where every knee bows to YHWH — and applies it to Christ (Philippians 2:9–11). Joel 2:32, “everyone who calls on the name of YHWH shall be saved,” becomes a declaration about Jesus in Romans 10:13. The author of Hebrews applies Psalm 102:25–27, a hymn addressed to YHWH as Creator, directly to the Son (Hebrews 1:10–12). This pattern — identifying Jesus with the God of Israel without abandoning monotheism — became the foundation of Trinitarian theology. As the early Fathers recognized, the New Testament does not replace YHWH with Jesus but reveals that the One who spoke from the burning bush and led Israel through the sea has now become flesh and dwelt among us (John 1:14; cf. 1 Corinthians 10:4).

The Name in Worship

The name YHWH is not merely theological information — it is an invitation to encounter the living God. The Psalms overflow with calls to praise, bless, and call upon “the name of the LORD” (Psalm 113:1–3; 145:1–2). To know His name is to know Him personally, to trust in His covenant character, and to find refuge in His unchanging faithfulness. The temple was the place where YHWH chose to make His name dwell (Deuteronomy 12:5; 1 Kings 8:29), and Israel’s worship centered on the proclamation, invocation, and praise of this name (Psalm 29:2; 96:8). In the new covenant, believers are baptized “in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28:19) — the one divine name now revealed as triune.

“Some trust in chariots and some in horses, but we trust in the name of the LORD our God.” — Psalm 20:7
