2 Kings 9:1-3

Now Elisha the prophet called one of the sons of the prophets and said to him, “Gird up your loins (prepare for action), take this flask of oil in your hand and go to Ramoth-gilead. When you arrive there, look for Jehu the son of Jehoshaphat the son of Nimshi, and go in and have him arise from among his brothers, and take him into 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.”
