2 Kings 10:1-3

1Now Ahab had seventy sons in Samaria. And Jehu wrote and sent letters to Samaria, to the rulers of Jezreel, to the elders, and to those who reared Ahab’s sons, saying:

2Now as soon as this letter comes to you, since your master’s sons are with you, and you have chariots and horses, a fortified city also, and weapons,

3choose the best qualified of your master’s sons, set him on his father’s throne, and fight for your master’s house.
