2 Kings 9:1-7

Then Elisha the prophet called one of the sons of the prophets and said to him, “Tie up your garments, and take this flask of oil in your hand, and go to Ramoth-gilead. And when you arrive, look there for Jehu the son of Jehoshaphat, son of Nimshi. And go in and have him rise from among his fellows, and lead him to an inner chamber. Then take the flask of oil and pour it on his head and say, ‘Thus says the LORD, I anoint you king over Israel.’ Then open the door and flee; do not linger.” So the young man, the servant of the prophet, went to Ramoth-gilead. And when he came, behold, the commanders of the army were in council. And he said, “I have a word for you, O commander.” And Jehu said, “To which of us all?” And he said, “To you, O commander.” So he arose and went into the house. And the young man poured the oil on his head, saying to him, “Thus says the LORD, the God of Israel, I anoint you king over the people of the LORD, over Israel. And you shall strike down the house of Ahab your master, so that I may avenge on Jezebel the blood of my servants the prophets, and the blood of all the servants of the LORD.
