2 Kings 10:1-3

1Since Ahab had seventy sons in Samaria, Jehu wrote letters and sent them to Samaria to the rulers of Jezreel, to the elders, and to the guardians of Ahab’s sons, saying:

2Your master’s sons are with you, and you have chariots, horses, a fortified city, and weaponry, so when this letter arrives

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