2 Kings 6:18-22

18When the Arameans came against him, Elisha prayed to the Lord, “Please strike this nation with blindness.” So he struck them with blindness, according to Elisha’s word.

19Then Elisha said to them, “This is not the way, and this is not the city. Follow me, and I will take you to the man you’re looking for.” And he led them to Samaria.

20When they entered Samaria, Elisha said, “Lord, open these men’s eyes and let them see.” So the Lord opened their eyes, and they saw that they were in the middle of Samaria.

21When the king of Israel saw them, he said to Elisha, “Should I kill them, should I kill them, my father?”

22Elisha replied, “Don’t kill them. Do you kill those you have captured with your sword or your bow? Set food and water in front of them so they can eat and drink and go to their master.”
