2 Kings 9:1-7

Now Elisha the prophet called one of the sons of the prophets and said to him, “Gird up your loins (prepare for action), take this flask of oil in your hand and go to Ramoth-gilead. When you arrive there, look for Jehu the son of Jehoshaphat the son of Nimshi, and go in and have him arise from among his brothers, and take him into an inner room. Then take the flask of oil and pour it on his head and say, ‘Thus says the LORD: “I have anointed you king over Israel.” ’ Then open the door and flee and do not delay.” So the young man, the servant of the prophet, went to Ramoth-gilead. When he arrived, the captains of the army were sitting [outside]; and he said, “I have a message for you, O captain.” Jehu said, “To which one of us?” And he said, “For you, O captain.” So Jehu got up, and they went into the house. And he poured the oil on Jehu’s head and said to him, “Thus says the LORD, the God of Israel: ‘I have anointed you king over the people of the LORD, over Israel. You shall strike the house of Ahab your master, so that I may avenge the blood of My servants the prophets, and the blood of all the servants of the LORD, [who have died] at the hands of Jezebel.
