[105] NOW Joram, the king of Israel, after the death of Benhadad, hoped that he might now take Ramoth, a city of Gilead, from the Syrians. Accordingly he made an expedition against it, with a great army; but as he was besieging it, an arrow was shot at him by one of the Syrians, but the wound was not mortal. So he returned to have his wound healed in Jezreel, but left his whole army in Ramorb, and Jehu, the son of Nimshi, for their general; for he had already taken the city by force; and he proposed, after he was healed,: to make war with the Syrians; but Elisha the prophet sent one of his disciples to Ramoth, and gave him holy oil to anoint Jehu, and to tell him that God had chosen him to be their king. He also sent him to say other things to him, and bid him to take his journey as if he fled, that when he came away he might escape the knowledge of all men. So when he was come to the city, he found Jehu sitting in the midst of the captains of the army, as Elisha had foretold he should find him. So he came up to him, and said that he desired to speak with him about certain matters; and when he was arisen, and had followed him into an inward chamber, the young man took the oil, and poured it on his head, and said that God ordained him to be king, in order to his destroying the house of Ahab, and that he might revenge the blood of the prophets that were unjustly slain by Jezebel, that so their house might utterly perish, as those of Jeroboam the son of Nebat, and of Baasha, had perished for their wickedness, and no seed might remain of Ahab's family. So when he had said this, he went away hastily out of the chamber, and endeavored not to be seen by any of the army.
