There was a man named Terah who lived in a place called Ur. He had three sons, and one of them was Abram. Now Abram was married to his half-sister Sarai, but they had no children.
Terah took Abram, Sarai, and his grandson Lot (who was an orphan) and moved north to a place called Haran. They stayed there until Terah died.
