1 Kings 11:19-21

New International Version

¹⁹ Pharaoh was so pleased with Hadad that he gave him a sister of his own wife, Queen Tahpenes, in marriage. ²⁰ The sister of Tahpenes bore him a son named Genubath, whom Tahpenes brought up in the royal palace. There Genubath lived with Pharaoh’s own children.

²¹ While he was in Egypt, Hadad heard that David rested with his ancestors and that Joab the commander of the army was also dead. Then Hadad said to Pharaoh, “Let me go, that I may return to my own country.”
