2 Kings 9:4-13

4So the young man, even the young man the prophet, went to Ramoth-gilead. 5And when he came, behold, the captains of the host were sitting; and he said, I have an errand to thee, O captain. And Jehu said, Unto which of us all? And he said, To thee, O captain. 6And he arose, and went into the house; and he poured the oil on his head, and said unto him, Thus saith Jehovah, the God of Israel, I have anointed thee king over the people of Jehovah, even over Israel. 7And thou shalt smite the house of Ahab thy master, that I may avenge the blood of my servants the prophets, and the blood of all the servants of Jehovah, at the hand of Jezebel. 8For the whole house of Ahab shall perish; and I will cut off from Ahab every man-child, and him that is shut up and him that is left at large in Israel. 9And I will make the house of Ahab like the house of Jeroboam the son of Nebat, and like the house of Baasha the son of Ahijah. 10And the dogs shall eat Jezebel in the portion of Jezreel, and there shall be none to bury her. And he opened the door, and fled.

11Then Jehu came forth to the servants of his lord: and one said unto him, Is all well? wherefore came this mad fellow to thee? And he said unto them, Ye know the man and what his talk was. 12And they said, It is false; tell us now. And he said, Thus and thus spake he to me, saying, Thus saith Jehovah, I have anointed thee king over Israel. 13Then they hasted, and took every man his garment, and put it under him on the top of the stairs, and blew the trumpet, saying, Jehu is king.
