2 Kings 6:17-22

17And Elisha prayed, “Open his eyes, LORD, so that he may see.” Then the LORD opened the servant’s eyes, and he looked and saw the hills full of horses and chariots of fire all around Elisha.

18As the enemy came down toward him, Elisha prayed to the LORD, “Strike this army with blindness.” So he struck them with blindness, as Elisha had asked.

19Elisha told them, “This is not the road and this is not the city. Follow me, and I will lead you to the man you are looking for.” And he led them to Samaria.

20After they entered the city, Elisha said, “ LORD, open the eyes of these men so they can see.” Then the LORD opened their eyes and they looked, and there they were, inside Samaria.

21When the king of Israel saw them, he asked Elisha, “Shall I kill them, my father? Shall I kill them?” 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.”
