18 As the Aramean army advanced toward him, Elisha prayed, "O Lord, please make them blind." So the Lord struck them with blindness as Elisha had asked. 19 Then Elisha went out and told them, "You have come the wrong way! This isn't the right city! Follow me, and I will take you to the man you are looking for." And he led them to the city of Samaria. 20 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. 21 When the king of Israel saw them, he shouted to Elisha, "My father, should I kill them? Should I kill them?" 22 "Of course not!" Elisha replied. "Do we kill prisoners of war? Give them food and drink and send them home again to their master." 23 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.

Commentary on 2 Kings 6:13-23
(Read 2 Kings 6:13-23)
What Elisha said to his servant is spoken to all the faithful servants of God, when without are fightings, and within are fears. Fear not, with that fear which has torment and amazement; for they that are with us, to protect us, are more than they that are against us, to destroy us. The eyes of his body were open, and with them he saw the danger. Lord, open the eyes of our faith, that with them we may see thy protecting hand. The clearer sight we have of the sovereignty and power of Heaven, the less we shall fear the troubles of earth. Satan, the god of this world, blinds men's eyes, and so deludes them unto their own ruin; but when God enlightens their eyes, they see themselves in the midst of their enemies, captives to Satan, and in danger of hell, though, before, they thought their condition good. When Elisha had the Syrians at his mercy, he made it appear that he was influenced by Divine goodness as well as Divine power. Let us not be overcome of evil, but overcome evil with good. The Syrians saw it was to no purpose to try to assault so great and so good a man.
