2 Chronicles 19:2 - Matthew Poole's English Annotations on the Holy Bible

Jehu the son of Hanani the seer; of whom see 1 Kings 16:1. Shouldest thou help the ungodly, and love them that hate the Lord? was this agreeable to thy duty and love which thou professest to God and godliness, that thou hast entered into so strict an alliance and friendship with wicked Ahab, my sworn enemy, and given such assistance to him? Therefore is wrath upon thee from before the Lord; therefore God is angry with thee, and will chastise thee for this miscarriage: which he did, partly, by stirring up the Moabites and others to invade him, 2Ch 20; partly, by permitting his eldest son Jehoram to kill all his brethren, 2 Chronicles 21:4; and principally, by bringing that sore and almost general destruction upon his grandchildren by Jehu, 2 Kings 9:27, 2 Kings 10:13,14, which was the proper fruit of his alliance with Ahab.
