2 Kings 6:18-23

And when the Syrians came down against him, Elisha prayed to the LORD and said, “Please strike this people with blindness.” So he struck them with blindness in accordance with the prayer of Elisha. And Elisha said to them, “This is not the way, and this is not the city. Follow me, and I will bring you to the man whom you seek.” And he led them to Samaria. As soon as they entered Samaria, Elisha said, “O LORD, open the eyes of these men, that they may see.” So the LORD opened their eyes and they saw, and behold, they were in the midst of Samaria. As soon as the king of Israel saw them, he said to Elisha, “My father, shall I strike them down? Shall I strike them down?” He answered, “You shall not strike them down. Would you strike down those whom 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 for them a great feast, and when they had eaten and drunk, he sent them away, and they went to their master. And the Syrians did not come again on raids into the land of Israel.
