Yahweh

“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 (ESV)

Definition

Yahweh (Hebrew יהוה, the Tetragrammaton, transliterated YHWH) is God’s personal name, revealed to Moses at the burning bush as “I AM WHO I AM” and given to Israel as his memorial name “forever” (Exod. 3:14-15). Built on the Hebrew verb “to be,” it declares that God exists from and for himself, always the same, and so able to keep every promise he makes.1 Ancient Jewish reverence stopped its pronunciation, substituting “Adonai” (“Lord”) instead, a practice the Septuagint’s Kyrios preserves and the New Testament inherits.1 “Jehovah” and “Yahweh” are both later attempts to recover that unspoken pronunciation.

Confessional Witness

The 1689 Second London Baptist Confession, following the Westminster Confession word for word, opens its account of God’s being with exactly the content Reformed exegetes read out of this name, without naming it directly: “The Lord our God is but one only living and true God; whose subsistence is in and of himself, infinite in being and perfection… immutable, immense, eternal, incomprehensible, almighty… most absolute.”2 The confession has no chapter devoted to the divine name as such. Reformed theologians make that connection explicitly. Calvin found the “eternity and self-existence” of God “declared by his magnificent name twice repeated” in Exodus 34:6-7, with “power and energy… comprehended under the name Jehovah.”3 Mastricht draws the same line from the name’s own etymology, tracing what the name Jehovah “denotes”:

God’s self-existence, by which he subsists through himself in such a way that he exists for all things as the cause of their existing and subsisting… his aseity, by which he alone is independent and uncaused, in such a way that for all creatures he is the source of being and existing.1

Gill’s contemporary Particular Baptist systematics reasons identically: the name is “expressive of the essence of God; of his necessary and self-existence, for God naturally and necessarily exists; which cannot be said of any other.”4

Biblical Basis

God first identifies himself to Moses by three names together: “the LORD [Yahweh], the God of your fathers… has sent me to you. This is my name forever, and this is my memorial from generation to generation” (Exod. 3:15). Mastricht reads the “essential name” here as itself a credential for Moses’s mission:

The one who, as he is from himself, is thus most perfect, who is faithful, not knowing how to be deceived or to deceive, who is steadfast and omnipotent, the one who is able both to make promises and to provide what has been promised.5

Exodus 6:2-3 recalls that the patriarchs already knew God by this name but not yet its full meaning, while Exodus 34:6-7’s proclamation (“The LORD, the LORD, a God merciful and gracious…”) ties the name directly to God’s covenant faithfulness. God calls it his own and refuses to share it: “I am the LORD; that is my name” (Isa. 42:8), and “his name alone is Jehovah” (Ps. 83:18).4

The New Testament applies the same name to Christ. Jesus takes it for himself directly: “before Abraham was, I am” (John 8:58), a claim Gill reads as a deliberate echo of Exodus 3:14.4 Mastricht catalogs a fuller set of Old Testament texts naming Christ Jehovah in the New Testament’s own reading of them: Psalm 102:25-27’s address to Jehovah is applied to the Son in Hebrews 1:10-12, and Psalm 68:18’s ascended Jehovah is applied to the Son in Ephesians 4:8-9.6

Doctrinal Significance

Bavinck describes Christian theology as having placed God’s aseity “in the foreground as the primary attribute traditionally associated with the name YHWH as given in Exodus 3:14.”7 For Israel specifically, the name is covenantal rather than a bare metaphysical claim. Quoting Dolezal, Parkison reads God’s “I AM” to Moses as “reassuring Moses and Israel of His all-sufficiency to accomplish the great work of their redemption from Egypt,” grounding “this perfect covenantal sufficiency on the perfect sufficiency of His own being, denoted by His name.”8 Bavinck reads the same declaration as a promise of constancy across redemptive history:

He will be what he was for the patriarchs, what he is now and will remain: he will be everything to and for his people… unchangeable in his grace, in his love, in his assistance.9

Charnock draws immutability from the very grammar of the name:

The name Jehovah signifies this attribute… I am, signifies his eternity; that, or the same that I am, his immutability… it never hath anything added to it, nor anything taken from it… it never changes its letters as other words do.10

(See Self-existence of God and Immutability of God for the fuller doctrinal treatment of each attribute the name grounds.)

Historical Development

From Tetragrammaton to “Jehovah” and “Yahweh”

Ancient Jewish reverence eventually stopped the name’s pronunciation altogether. Mastricht reports the rabbinic reading of Exodus 3:15’s “forever” as related to a word for “to conceal,” taken to mean the name “must be concealed,” so that Adonai or Elohim were read aloud in its place.5 Bavinck traces the same practice into Greek: the Septuagint renders YHWH as Kyrios rather than transliterating it, “and the New Testament follows suit.”9 When Christian scholars later added vowel points to the Hebrew text, they attached Adonai’s vowels to YHWH’s consonants as a reading cue, a hybrid form later Christian scholarship read as a word in its own right and rendered “Jehovah.”1 Modern scholarship instead reconstructs the name’s likely original pronunciation as “Yahweh,” from the same Hebrew root for “to be” that both Gill and Mastricht trace it to.4

Reformed exposition of the name

Calvin’s Institutes (1559) and his commentary on Exodus both make the name load-bearing for the doctrine of God. Beyond the “eternity and self-existence” Calvin found in Exodus 34, his commentary on Exodus 3:14 argued the point grammatically: the Hebrew verb behind the name, though future in form, “is of the same force as the present, [and] designates the perpetual duration of time,” so that God “attributes to himself alone divine glory, because he is self-existent and therefore eternal.”11 Later Reformed orthodoxy inherited and systematized this reading. Turretin, teaching in Geneva a century after Calvin, built his own proof of God’s essence and existence around “a proper exposition of the divine names,” giving the Tetragrammaton “the position of prominence.”12 Mastricht devoted a full chapter of his own theology to the divine names, opening with Exodus 3:15 as his text and treating Jehovah first among them.5 Gill, the Particular Baptist theologian whose systematics stands in the same confessional tradition as the 1689 LBCF, and Charnock both gave the name its own extended treatment: Gill traced its Old and New Testament uses and its bearing on Christ,4 and Charnock returned to it across separate discourses on God’s eternity and immutability.13

Objections and Responses

Isn’t “Jehovah” simply a scholarly mistake, a hybrid formed by reading Adonai’s vowels onto YHWH’s consonants? The vowel hybrid arose from a real substitution practice, not a claim to preserve the name’s original sound: Jewish readers had long substituted Adonai (or Elohim) aloud for YHWH out of reverence, and the borrowed vowel points were originally only a cue for that substitution, not an attempt to spell a new word.1 “Jehovah” and “Yahweh” are both later attempts to recover a pronunciation Israel itself stopped using; neither rendering changes what the name’s own Hebrew root and the text’s own exposition of it (Exod. 3:14-15; 34:6-7) say about God.

If the name is God’s own and “incommunicable to another” (Ps. 83:18), how can Ezekiel name the restored city “Jehovah-shammah” (“the LORD is there,” Ezek. 48:35)? Gill answers that such uses are relational, not proper: the name is sometimes “spoken of another, yet not singly and properly, but with relation to him,” as when a place is named for God’s presence there rather than treated as itself divine.4

Does John 8:58 (“before Abraham was, I am”) really invoke Exodus 3:14, or is this reading too much into an ordinary turn of phrase? Gill treats it as a deliberate echo, not coincidence. Having already shown that the name God gave Moses (“I AM,” Exod. 3:14) is “of the same signification with Jehovah,” Gill states: “our Lord has a manifest respect unto it, when he says, ‘Before Abraham was I AM.’”4 Mastricht’s own list of divine names Scripture applies to the Son treats Jehovah as the first and most decisive of them.6
