2 Kings 6:31-32

31He said, “May God deal with me, be it ever so severely, if the head of Elisha son of Shaphat remains on his shoulders today!”

32Now Elisha was sitting in his house, and the elders were sitting with him. The king sent a messenger ahead, but before he arrived, Elisha said to the elders, “Don’t you see how this murderer is sending someone to cut off my head? Look, when the messenger comes, shut the door and hold it shut against him. Is not the sound of his master’s footsteps behind him?”
