“father.” We would normally think that the word should be plural, “fathers.” But in this case, the word is singular to emphasize the covenant that God made individually with Abraham and then reconfirmed with Isaac and Jacob (see commentary on Genesis 17:8). The word “father” here does not refer to Amram, Moses’ actual father (Exod. 6:20), but rather to the “fathers of the Faith,” i.e., Abraham, Isaac, and Jacob.
