According to the Bible, Jehu condemned Baasha, king of Israel, "and his house" (1 Kings 16:7), accusing him of leading the people into the sin of idolatry like his predecessor Jeroboam. Jehu foretold that:
- surely [God] will take away the posterity of Baasha and the posterity of his house, and ... will make your house like the house of Jeroboam the son of Nebat. The dogs shall eat whoever belongs to Baasha and dies in the city, and the birds of the air shall eat whoever dies in the fields.
Jehu also challenged Jehoshaphat, king of Judah. Jehoshaphat's alliance with Ahab ended in the latter's death at the Battle of Ramoth-Gilead. Jehoshaphat returned safely, but Jehu rebuked him for helping the wicked king Ahab. He went on to say that nevertheless the Lord found good in the king, as he had removed the Asherah poles from the land and set his heart to seek God. (2 Chronicles 19:2-3)
