One day Terah took his son Abram, his daughter-in-law Sarai (his son Abram’s wife), and his grandson Lot (his son Haran’s child) and moved away from Ur of the Chaldeans. He was headed for the land of Canaan, but they stopped at Haran and settled there.
So Sarai, Abram’s wife, took Hagar the Egyptian servant and gave her to Abram as a wife. (This happened ten years after Abram had settled in the land of Canaan.)
It was by faith that Abraham obeyed when God called him to leave home and go to another land that God would give him as his inheritance. He went without knowing where he was going.
