2 Kings 9:1-3

1And Elisha the prophet called one of the sons of the prophets, and said to him, Gird up thy loins, and take this vial of oil in thy hand, and go to Ramoth-Gilead.

2And when thou art come thither, look out there Jehu the son of Jehoshaphat, son of Nimshi, and go in, and make him rise up from among his brethren, and bring him to an inner chamber;

3then take the vial of oil, and pour it on his head and say, Thus saith Jehovah: I have anointed thee king over Israel; and open the door, and flee, and tarry not.
