Jehu becomes king of Israel and Joash becomes king of Judah.  Consider:

• God’s Sovereignty – God said that Ahab’s family would be destroyed, and it was. God pulls down dynasties (like Ahab’s) and raises up new kings (like Jehu).  God is clearly in control.  How does this truth help you as you see the events of our world today?
• Need of Instruction – Joash did what was right because he had someone to instruct him (12:2). Who is instructing you in the way of the Lord?  Do you listen to the instruction you receive?  Take time to pray for and thank God for those who instruct you.  Who are you instructing?
