And he said unto the king of Israel, put thine hand upon the
bow, and he put his hand upon it
His left hand:
and Elisha put his hands upon the king's hands;
on both his hands, which were put, the one on the bow, the other on the arrow F13; hereby signifying, that though the king would draw the bow in battle, the Lord, whom the prophet represented, would give the success; and that it would be by his help, and through his blessing on his arms, that he would obtain victory over his enemies.
F13 See Virgil. Aeneid. 11. ver. 831, 862.
