2 Kings 10:1-3

1Now Ahab had seventy sons in Samaria. And Jehu wrote letters, and sent to Samaria, to the princes of Jizreel, to the elders, and to Ahab's guardians, saying,

2And now, when this letter comes to you, seeing your master's sons are with you, and there are with you chariots, and horses, and a fortified city, and armour,

3look out the best and worthiest of your master's sons, and set him on his father's throne, and fight for your master's house.
