Genesis 25:19 Meaning and Commentary

Genesis 25:19

And these [are] the generations of Isaac, Abraham's son
Moses, having given the genealogy of Ishmael and his posterity, returns to Isaac, the other son of Abraham, with whom and his children the following part of his history is chiefly, if not altogether concerned: Abraham begat Isaac;
for the further confirmation of his being his proper legitimate son this clause is added.

Genesis 25:19 In-Context

17 Ishmael was 137 years old when he died.

18 The descendants of Ishmael lived in the territory between Havilah and Shur, to the east of Egypt on the way to Assyria. They lived apart from the other descendants of Abraham.

19 This is the story of Abraham's son Isaac.

20 Isaac was forty years old when he married Rebecca, the daughter of Bethuel (an Aramean from Mesopotamia) and sister of Laban.

21 Because Rebecca had no children, Isaac prayed to the Lord for her. The Lord answered his prayer, and Rebecca became pregnant.
