1 Kings 11:17-22

17that Hadad escaped to Egypt, he and some Edomites from his father’s servants with him, while Hadad was [still] a little boy.

18They set out from Midian [south of Edom] and came to Paran, and took men with them from Paran and came to Egypt, to Pharaoh king of Egypt, who gave [young] Hadad a house and ordered food and provisions for him and gave him land.

19Hadad found great favor with Pharaoh, so that he gave Hadad in marriage the sister of his own wife, the sister of Tahpenes the queen.

20The sister of Tahpenes gave birth to Genubath, Hadad’s son, whom Tahpenes weaned in Pharaoh’s house; and Genubath was in Pharaoh’s household among the sons of Pharaoh.

21But when Hadad heard in Egypt that David had died and that Joab the commander of the army was dead, Hadad said to Pharaoh, “Let me leave, so that I may go to my own country.”

22Then Pharaoh said to him, “But what have you lacked with me that now you ask to go to your own country?” He replied, “Nothing; nevertheless you must let me go.”
