1 Kings 11:17 WEB

¹⁵  For it happened, when David was in Edom, and Joab the captain of the host was gone up to bury the slain, and had struck every male in Edom

¹⁶  (for Joab and all Israel remained there six months, until he had cut off every male in Edom);

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

¹⁸  They arose out of Midian, and came to Paran; and they 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 food, and gave him land.

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