2 Kings 10
There were seventy descendants of King Ahab living in the city of Samaria. Jehu wrote a letter and sent copies to the rulers of the city, to the leading citizens, and to the guardians of Ahab's descendants. The letter read: 2 “You are in charge of the king's descendants, and you have at your disposal chariots, horses, weapons, and fortified cities. So then, as soon as you receive this letter, 3 you are to choose the best qualified of the king's descendants, make him king, and fight to defend him.”
4 The rulers of Samaria were terrified. “How can we oppose Jehu,” they said, “when neither King Joram nor King Ahaziah could?” 5 So the officer in charge of the palace and the official in charge of the city, together with the leading citizens and the guardians, sent this message to Jehu: “We are your servants, and we are ready to do anything you say. But we will not make anyone king; do whatever you think best.”
6 Jehu wrote them another letter: “If you are with me and are ready to follow my orders, bring the heads of King Ahab's descendants to me at Jezreel by this time tomorrow.”
The seventy descendants of King Ahab were under the care of the leading citizens of Samaria, who were bringing them up. 7 When Jehu's letter was received, the leaders of Samaria killed all seventy of Ahab's descendants, put their heads in baskets, and sent them to Jehu at Jezreel.
