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 And the years of [the] life of Ishmael were made an hundred and seven and thirty (years), and (then) he failed, and died, and was put to his people (and joined his ancestors).

18 Forsooth he inhabited from Havilah till to Shur, that beholdeth Egypt, as men entereth into [the] Assyrians; (and) he died before all his brethren. (And Ishmael's people dwelled from Havilah unto Shur, which is east of Egypt, on the way to Assyria; and he died in the presence of all his kinsmen.)

19 Also these be the generations of Isaac, the son of Abraham. Abraham begat Isaac, (And these be the descendants of Isaac, Abraham's son. Abraham begat Isaac,)

20 and when Isaac was of forty years, he wedded a wife, Rebecca, the daughter of Bethuel, of Syria, of Mesopotamia, the sister of Laban. (and when Isaac was forty years old, he wedded a wife, Rebecca, the daughter of Bethuel, the Syrian from Paddan-aram, and the sister of Laban.)

21 And Isaac besought the Lord for his wife, for she was barren; and the Lord heard him, and gave conceiving to Rebecca.
