1 Kings 11:18-20

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

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

20And the sister of Tahpenes bore him Genubath his son; and Tahpenes brought him up in Pharaoh's house; and Genubath was in Pharaoh's household, among the sons of Pharaoh.
