did evil in the sight of the LORD: He married Ahab's daughter, Athaliah, and followed the kings of Israel by worshiping idols. Some believe Psalm 45 was written for Jehoram and Athaliah's marriage, which united the royal families of Judah and Israel (see Psalm 45:12; Athaliah was Jezebel's daughter, the princess of Tyre).
Although the marriage temporarily united the kingdoms, it led to terrible spiritual consequences. Influenced by Athaliah, Jehoram introduced false worship practices (2 Chronicles 21:11), including Baal worship (2 Kings 11:17–18).
