Genesis 11:31

And Terah took Abram, his son, and Lot, the son of Haran, his son's son, and Sarai, his daughter-in-law, his son Abram's wife; and they went forth with them from Ur of the Chaldees to go into the land of Canaan; and they came unto Haran and dwelt there. These all went forth together, or with one another, under the leadership of Terah and Abram. In the case of Abram, he had, even now, received God's command to journey forth, Acts 7:3, while in the case of Terah the migration was a part of God's dispensation, the first step of the journey which would bring Abram to the land of his inheritance.
