Hadad

When King David's army defeated the Edomites, Hadad, a prince of Edom, escaped to Egypt. There "Hadad found great favor in the sight of the Pharaoh", who gave him both land and a house, allowance for food, and the hand of his wife's sister in marriage. After King David died, Hadad became an enemy of King Solomon.

The name Hadad means "thunderer."
