Isaac
Family life

Before Isaac was 40 (Genesis 25:20), Abraham sent Eliezer, his steward, into Mesopotamia to find a wife for Isaac, from his nephew Bethuel 's family. Eliezer chose the Aramean Rebekah for Isaac. After many years of marriage to Isaac, Rebekah had still not given birth to a child and was believed to be barren. Isaac prayed for her and she conceived. Rebekah gave birth to twin boys, Esau and Jacob. Isaac was 60 years old when his two sons were born. Isaac favored Esau, and Rebekah favored Jacob.

The narratives about Isaac do not mention his having concubines.
