“I Yahweh am the God of Abraham, and the God of Isaac, and the God of Jacob.” Jesus uses this verse to show that the Torah teaches a resurrection from the dead. God did not say that He “had been” the God of Abraham, Isaac and Jacob, but rather that he was the God of Abraham, Isaac and Jacob. That is, that he was still their God, and would actively be so when they were raised from the dead. Some would say that the present tense of the verb proves that Abraham, Isaac, and Jacob were alive in heaven at that time (and now), but the context is clearly “the resurrection,” (used four times in the context: Matt. 22:23, 27, 30, 31).
“Yahweh.” The name “Yahweh” appears in the Hebrew text of Matthew. Yahweh is the personal name of God, and a rabbinic abbreviation for it appears in the Hebrew manuscript of Matthew. There is evidence that Matthew wrote his Gospel in Hebrew and used the name Yahweh, so we have put it in the REV (see commentary on Matthew 3:3).
