2 Kings 9-12 (The Daily Walk Bible).
Jehu is an interesting king of Israel, and his circumstances show God’s sovereignty. God even uses the ungodly to accomplish his purposes!
2 Kings 10:31-31 “And the Lord said to Jehu, ‘Because you have done well in carrying out what is right in my eyes, and have done to the house of Ahab according to all that was in my heart, your sons of the fourth generation shall sit on the throne of Israel.’ But Jehu was not careful to walk in the law of the Lord, the God of Israel, with all his heart. He did not turn from the sins of Jeroboam, which he made Israel to sin.”
Unfortunately Jehu carried on the tradition of the northern kings not following God.
