2 Kings 13:17

And he said, Open the window eastward, that being the direction in which the enemies lived. And he opened it. Then Elisha said, Shoot. And he shot. And he, Elisha, said, while the arrow was speeding forward, The arrow of the Lord's deliverance and the arrow of deliverance from Syria; the arrow was a symbol of the deliverance which Jehovah would surely give, and it was a pledge of Jehovah against the forces of Syria; for thou shalt smite the Syrians in Aphek till thou have consumed them, they would suffer a decisive defeat.
