18 When the Arameans attacked, Elisha prayed to God, "Strike these people blind!" And God struck them blind, just as Elisha said. 19 Then Elisha called out to them, "Not that way! Not this city! Follow me and I'll lead you to the man you're looking for." And he led them into Samaria. 20 As they entered the city, Elisha prayed, "O God, open their eyes so they can see where they are." God opened their eyes. They looked around - they were trapped in Samaria! 21 When the king of Israel saw them, he said to Elisha, "Father, shall I massacre the lot?" 22 "Not on your life!" said Elisha. "You didn't lift a hand to capture them, and now you're going to kill them? No sir, make a feast for them and send them back to their master." 23 So he prepared a huge feast for them. After they ate and drank their fill he dismissed them. Then they returned home to their master. The raiding bands of Aram didn't bother Israel anymore.

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.
