1 Kings 11:18 KJV

16(For six months did Joab remain there with all Israel, until he had cut off every male in Edom:)

17That Hadad fled, he and certain Edomites of his father’s servants with him, to go into Egypt; Hadad being yet a little child.

18And they arose out of Midian, and came to Paran: and they took men with them out of Paran, and they came to Egypt, unto Pharaoh king of Egypt; which gave him an house, and appointed him victuals, and gave him land.

19And Hadad found great favour in the sight of Pharaoh, so that he gave him to wife the sister of his own wife, the sister of Tahpenes the queen.

20And the sister of Tahpenes bare him Genubath his son, whom Tahpenes weaned in Pharaoh’s house: and Genubath was in Pharaoh’s household among the sons of Pharaoh.
