2 Kings 9:1-3

And Elisha the prophet called one of the children of the prophets, and said unto him, Gird up thy loins, and take this box of oil in thine hand, and go to Ramoth-gilead: and when thou comest thither, look out there Jehu the son of Jehoshaphat the son of Nimshi, and go in, and make him arise up from among his brethren, and carry him to an inner chamber; then take the box of oil, and pour it on his head, and say, Thus saith the LORD, I have anointed thee king over Israel. Then open the door, and flee, and tarry not.
