2 Kings 10
5 Ref So the controller of the king's house, with the ruler of the town, and the responsible men, and those who had the care of Ahab's sons, sent to Jehu, saying, We are your servants and will do all your orders; we will not make any man king; do whatever seems best to you.
6 Ref Then he sent them a second letter, saying, If you are on my side, and if you will do my orders, come to me at Jezreel by this time tomorrow, with the heads of your master's sons. Now the king's seventy sons were with the great men of the town, who had the care of them.
7 Ref And when the letter came to them, they took the king's sons and put them to death, all the seventy, and put their heads in baskets and sent them to him at Jezreel.
