14 So he sent there horses and chariots and a great army; and they came by night, and surrounded the city. 15 When the servant of the man of God rose early in the morning and went out, behold, an army with horses and chariots was round about the city. And the servant said, "Alas, my master! What shall we do?" 16 He said, "Fear not, for those who are with us are more than those who are with them." 17 Then Eli'sha prayed, and said, "O Lord, I pray thee, open his eyes that he may see." So the Lord opened the eyes of the young man, and he saw; and behold, the mountain was full of horses and chariots of fire round about Eli'sha. 18 And when the Syrians came down against him, Eli'sha prayed to the Lord, and said, "Strike this people, I pray thee, with blindness." So he struck them with blindness in accordance with the prayer of Eli'sha.

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.
