2 Kings 6:22-23

22“Do not kill them,” he answered. “Would you kill those you have captured with your own sword or bow? Set food and water before them so that they may eat and drink and then go back to their master.”

23So he prepared a great feast for them, and after they had finished eating and drinking, he sent them away, and they returned to their master. So the bands from Aram stopped raiding Israel’s territory.
