And Abram and Nahor took 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 Iscah.
Here begins the story of Abram, whose name is famous, henceforward, in both Testaments. We have here, I. His country: Ur of the Chaldees. This was the land of his nativity, an idolatrous country, where even the children of Eber themselves had degenerated.
Commenting on Genesis 11:27-32
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. (m) Some think that this Iscah was Sarai.
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.
