The Chronicler’s account is based on 2 Kings 8:25-29. Ahaziah formed alliances with the northern kingdom and was disliked by God. All evil came from that kingdom, which was influenced by the Phoenicians. Kinship, alliances, examples, and advice also led the king of Judah astray (vs. 3-5). The chapter ends with Athaliah’s crime and the skill of Jehosheba, who protected Joash to keep David’s lineage alive (see 2 Kgs 11:1-3).
