1 Kings 11:14-20

Then the LORD raised up Hadad the Edomite, a member of Edom’s royal family, to be Solomon’s adversary. Years before, David had defeated Edom. Joab, his army commander, had stayed to bury some of the Israelite soldiers who had died in battle. While there, they killed every male in Edom. Joab and the army of Israel had stayed there for six months, killing them. But Hadad and a few of his father’s royal officials escaped and headed for Egypt. (Hadad was just a boy at the time.) They set out from Midian and went to Paran, where others joined them. Then they traveled to Egypt and went to Pharaoh, who gave them a home, food, and some land. Pharaoh grew very fond of Hadad, and he gave him his wife’s sister in marriage—the sister of Queen Tahpenes. She bore him a son named Genubath. Tahpenes raised him in Pharaoh’s palace among Pharaoh’s own sons.
