Genesis 11:29-31

29Abram married Sarai. Nahor married Milcah. Milcah was Haran's daughter. Haran was the father of Milcah and Iscah.

30Sarai could not give birth to children. She did not have any children.

31Terah took his son Abram and his grandson Lot. (Lot was Haran's son.) Terah also took Abram's wife Sarai. They all left Ur, the land of the Chaldeans. They began to go to Canaan. But when they came to Haran, they stayed there.
