2nd Kings 9:5

2 When you come there, look out there Jehu the son of Jehoshaphat the son of Nimshi, and go in, and make him arise up from among his brothers, and carry him to an inner chamber.

3 Then take the vial of oil, and pour it on his head, and say, Thus says Yahweh, I have anointed you king over Israel. Then open the door, and flee, and don`t wait.

4 So the young man, even the young man the prophet, went to Ramoth-gilead.

5 When he came, behold, the captains of the host were sitting; and he said, I have an errand to you, captain. Jehu said, To which of us all? He said, To you, O captain.

6 He arose, and went into the house; and he poured the oil on his head, and said to him, Thus says Yahweh, the God of Israel, I have anointed you king over the people of Yahweh, even over Israel.

7 You shall strike the house of Ahab your master, that I may avenge the blood of my servants the prophets, and the blood of all the servants of Yahweh, at the hand of Jezebel.

8 For the whole house of Ahab shall perish; and I will cut off from Ahab every man-child, and him who is shut up and him who is left at large in Israel.
