After this Jehoshaphat king of Judah allied himself with Ahaziah king of Israel, who acted very wickedly.
for he served Baal and worshiped him, and provoked the Lord God of Israel to anger, according to all that his father had done.
Jehoshaphat had riches and honor in abundance; and by marriage he allied himself with Ahab.
And he walked in the way of the kings of Israel, just as the house of Ahab had done, for he had the daughter of Ahab as a wife; and he did evil in the sight of the Lord.
