“Know then that there shall fall to the earth nothing of the word of the LORD” (10:10). Jehu acted out the justice of God against the household and descendants of King Ahab and Queen Jezebel of Israel. This family had slaughtered God’s prophets, promoted the worship of Baal, and caused the whole land to suffer. “There was none who sold himself to do what was evil in the sight of the LORD like Ahab, whom Jezebel his wife incited” (I Kings 21:25-26). Elijah had prophesied their total destruction.
Ahab and Jezebel thought that they were above God’s law. But God sees the oppression of the innocent, and we can trust that His justice is perfect (Deut 10:18).
