II Kings 9:1-3

And Elisha the prophet called one of the sons of the prophets, and said to him, “Get yourself ready, take this flask of oil in your hand, and go to Ramoth Gilead. Now when you arrive at that place, look there for Jehu the son of Jehoshaphat, the son of Nimshi, and go in and make him rise up from among his associates, and take him to an inner room. Then take the flask of oil, and pour it on his head, and say, ‘Thus says the LORD: “I have anointed you king over Israel.” ’ Then open the door and flee, and do not delay.”
