2 Kings 6:21-23

Then the king of Israel when he saw them, said to Elisha, “My father, shall I kill them? Shall I kill them?” He answered, “You shall not kill them. Would you kill those you have taken captive with your sword and with your bow? Set bread and water before them, that they may eat and drink and go to their master.” So he prepared a great feast for them; and when they had eaten and drunk he sent them away, and they went to their master. And the marauding bands of Arameans did not come again into the land of Israel.
