1 Kings 11:14-20

And the LORD raised up an adversary against Solomon, Hadad the Edomite. He was of the royal house in Edom. For when David was in Edom, and Joab the commander of the army went up to bury the slain, he struck down every male in Edom (for Joab and all Israel remained there six months, until he had cut off every male in Edom). But Hadad fled to Egypt, together with certain Edomites of his father’s servants, Hadad still being a little child. They set out from Midian and came to Paran and took men with them from Paran and came to Egypt, to Pharaoh king of Egypt, who gave him a house and assigned him an allowance of food and gave him land. And Hadad found great favor in the sight of Pharaoh, so that he gave him in marriage the sister of his own wife, the sister of Tahpenes the queen. And the sister of Tahpenes bore him Genubath his son, whom Tahpenes weaned in Pharaoh’s house. And Genubath was in Pharaoh’s house among the sons of Pharaoh.
