2 Kings 6:31-32

31Then he said, “May God do so to me and more also, if the head of Elisha the son of Shaphat remains on him today!”

32Now Elisha was sitting in his house, and the elders were sitting with him. And the king sent a man ahead of him [to behead Elisha]; but before the messenger arrived, Elisha told the elders, “Do you see how this son of [Jezebel] a murderer has sent [a man] to remove my head? Look, when the messenger comes, shut the door and hold it securely against him. Is not the sound of his master’s feet [just] behind him?”
