25:12 This is the account of Abraham’s son Ishmael, 1 whom Hagar the Egyptian, Sarah’s servant, bore to Abraham.
25:19 This is the account of Isaac, 2 the son of Abraham.

1 sn This is the account of Ishmael. The Book of Genesis tends to tidy up the family records at every turning point. Here, before proceeding with the story of Isaac’s family, the narrative traces Ishmael’s family line. Later, before discussing Jacob’s family, the narrative traces Esau’s family line (see Gen 36).
2 sn This is the account of Isaac. What follows for several chapters is not the account of Isaac, except briefly, but the account of Jacob and Esau. The next chapters tell what became of Isaac and his family.
