1 Kings 11:20-21

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.”
