Genesis 33:20

33:20 There he set up an altar and called it “The God of Israel is God.” ¹ 

Exodus 3:15

3:15 God also said to Moses, “You must say this to the Israelites, ‘The Lord ²  – the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob – has sent me to you. This is my name ³  forever, and this is my memorial from generation to generation.’ ⁴ 

[33:20]  ¹ tn Heb “God, the God of Israel.” Rather than translating the name, a number of modern translations merely transliterate it from the Hebrew as “El Elohe Israel” (cf. NIV, NRSV, REB). It is not entirely clear how the name should be interpreted grammatically. One option is to supply an equative verb, as in the translation: “The God of Israel [is] God.” Another interpretive option is “the God of Israel [is] strong [or “mighty”].” Buying the land and settling down for a while was a momentous step for the patriarch, so the commemorative naming of the altar is significant.

[3:15]  ² sn Heb “Yahweh,” traditionally rendered “the Lord.” First the verb “I AM” was used (v. 14) in place of the name to indicate its meaning and to remind Moses of God’s promise to be with him (v. 12). Now in v. 15 the actual name is used for clear identification: “Yahweh…has sent me.” This is the name that the patriarchs invoked and proclaimed in the land of Canaan.

[3:15]  ³ sn The words “name” and “memorial” are at the heart of the two parallel clauses that form a poetic pair. The Hebrew word “remembrance” is a poetical synonym for “name” (cf. Job 18:17; Ps 135:13; Prov 10:7; Isa 26:8) and conveys the idea that the nature or character of the person is to be remembered and praised (S. R. Driver, Exodus, 24).

[3:15]  ⁴ tn The repetition of “generation” in this expression serves as a periphrasis for the superlative: “to the remotest generation” (GKC 432 §133.l).
