Genesis 11:29 - Clarke's commentary and critical notes on the Bible

And Abram and Nahor took them wives: the name of Abram's wife was Sarai; and the name of Nahor's wife, Milcah, the daughter of Haran, the father of Milcah, and the father of Iscah. Milcah, the daughter of Haran - Many suppose Sarai and Iscah are the same person under two different names; but this is improbable, as Iscah is expressly said to be the daughter of Haran, and Sarai was the daughter of Terah, and half sister of Abram.
