Hadad

Then ADONAI raised up an adversary against Shlomo, Hadad the Edomi, of the royal line of Edom.

Hadad had fled, he and a number of Edomi servants of his father's with him, and gone into Egypt; at the time Hadad had been but a small boy.

Hadad became a great favorite of Pharaoh, so that he gave him his own wife's sister in marriage, that is, the sister of Tachp'neis the queen.

When Hadad in Egypt heard that David slept with his ancestors and Yo'av the commander of the army was dead, Hadad said to Pharaoh, "Let me leave, so that I can return to my own country."

He remained an adversary as long as Shlomo lived, causing difficulties in addition to those of Hadad. He detested Isra'el and ruled Aram.
