2 Kings 6:20-23

As soon as they had entered Samaria, Elisha prayed, “O LORD, now open their eyes and let them see.” So the LORD opened their eyes, and they discovered that they were in the middle of Samaria. When the king of Israel saw them, he shouted to Elisha, “My father, should I kill them? Should I kill them?” “Of course not!” Elisha replied. “Do we kill prisoners of war? Give them food and drink and send them home again to their master.” So the king made a great feast for them and then sent them home to their master. After that, the Aramean raiders stayed away from the land of Israel.
