2 Kings 6:22-23

6:22 He replied, “Do not strike them down! You did not capture them with your sword or bow, so what gives you the right to strike them down? Give them some food and water, so they can eat and drink and then go back to their master.” 6:23 So he threw a big banquet for them and they ate and drank. Then he sent them back to their master. After that no Syrian raiding parties again invaded the land of Israel.
