1 Kings 11:15-18

15Earlier, when David was at war with Edom, Joab, commander of the army, went up to bury the slain, and had struck down every male in Edom.

16Joab and all Israel remained there six months, until he had cut off every male in Edom.

17But Hadad and some Edomites, servants of his father, had fled to Egypt, while Hadad was a small boy.

18Setting out from Midian they came to Paran and took men from Paran along with them, and went to Egypt—to Pharaoh king of Egypt—who gave him a house, allotted him food and gave him land.
