2 Chronicles 18:1

Now, Jehoshaphat had riches and honor in abundance, as described in detail in the preceding chapter, and joined affinity with Ahab, entered into a formal league or alliance with him, which was cemented, moreover, by the marriage of Athaliah, the daughter of Ahab, to Jehoram, the son of Jehoshaphat. But neither the league nor the matrimonial alliance which brought the two reigning houses into closer union met with the approval of the Lord, 2 Chronicles 19:2.
