After this did Yehoshafat king of Yehudah join himself with Achazyah king of Yisra'el; the same did very wickedly:
He served Ba`al, and worshiped him, and provoked to anger the LORD, the God of Yisra'el, according to all that his father had done.
Now Yehoshafat had riches and honor in abundance; and he joined affinity with Ach'av.
He walked in the way of the kings of Yisra'el, as did the house of Ach'av; for he had the daughter of Ach'av as wife: and he did that which was evil in the sight of the LORD.
