20. The sister of Tahpenes bore his son Genubath, whom Tahpenes weaned in Pharaoh's house; and Genubath was in Pharaoh's house among the sons of Pharaoh.
21. But when Hadad heard in Egypt that David slept with his fathers and that Joab the commander of the army was dead, Hadad said to Pharaoh, "Send me away, that I may go to my own country."
22. Then Pharaoh said to him, "But what have you lacked with me, that behold, you are seeking to go to your own country?" And he answered, "Nothing; nevertheless you must surely let me go."
