18 When they came down to him, Elisha prayed to Yahweh, and said, “Please strike this people with blindness.”
He struck them with blindness according to the word of Elisha. 19 Elisha said to them, “This is not the way, neither is this the city. Follow me, and I will bring you to the man whom you seek.” He led them to Samaria. 20 It happened, when they were come into Samaria, that Elisha said, “Yahweh, open the eyes of these men, that they may see.”
Yahweh opened their eyes, and they saw; and behold, they were in the midst of Samaria. 21 The king of Israel said to Elisha, when he saw them, “My father, shall I strike them? Shall I strike them?” 22 He answered, “You shall not strike them. Would you strike 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.” 23 He prepared great feast for them. When they had eaten and drunk, he sent them away, and they went to their master. The bands of Syria stopped raiding 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.
