2 Kings 10:1-3

Ahab had seventy sons still living in Samaria. Jehu wrote letters addressed to the officers of Jezreel, the city elders, and those in charge of Ahab’s sons, and posted them to Samaria. The letters read: This letter is fair warning. You’re in charge of your master’s children, chariots, horses, fortifications, and weapons. Pick the best and most capable of your master’s sons and put him on the throne. Prepare to fight for your master’s position.
