6 So Jehu sent a second letter to them, writing this: “If you ◄are on my side/want to help me►, and if you are ready to obey me, [kill] King Ahab’s descendants [and cut off their heads and] bring their heads to me here in Jezreel at this time tomorrow.” The seventy descendants of King Ahab were being brought up and supervised by the leaders of [Samaria] city.
