Hadad found great favour in the sight of Pharaoh God so disposing Pharaoh's heart, that Hadad might be a scourge to Solomon for his impieties. Here Hadad married the sister of Tahpenes the queen, who bare him a son. Whom Tahpenes weaned in Pharaoh's house Having as great a fondness for the child, as the king had for his father; and kept the feast generally made at the weaning of a child. In all these things the providence of God was conspicuous, thus causing Hadad and his family to rise into power and influence, that he might give the greater trouble to Solomon.
