Elisha said, "Open the east window." So he opened it. Elisha said, "Shoot!" So he shot. Then Elisha said, "The Lord's arrow of victory, yes, the arrow of victory over Aram. You are to strike down the Arameans in Aphek until you have put an end to them."
Then Elisha said, "Take the arrows!" So he took them, and he said to the king of Israel, "Strike the ground!" So he struck the ground three times and stopped.
The man of God was angry with him and said, "You should have struck the ground five or six times. Then you would have struck down Aram until you had put an end to them, but now you will only strike down Aram three times."
