Genesis 11:29

29. Iscah is, by Josephus, ( Ant . , 1: 6,) and by the Jewish writers generally, identified with Sarai or Sarah . If so, Abram married his niece, and Lot was his brother-in-law as well as his nephew . See the plan under Genesis 11:27. That Sarah was in some way descended from Terah appears from Abram’s statement to Abimelech, Genesis 20:12, “She is the daughter of my father, but not the daughter of my mother . ”
