3:15 God also said to Moses, “You must say this to the Israelites, ‘The Lord49—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 name50 forever, and this is my memorial from generation to generation.’51
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.
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).
