2 Kings 6:13-18 ESV
And he said, “Go and see where he is, that I may send and seize him.” It was told him, “Behold, he is in Dothan.” So he sent there horses and chariots and a great army, and they came by night and surrounded the city.
When the servant of the man of God rose early in the morning and went out, behold, an army with horses and chariots was all around the city. And the servant said, “Alas, my master! What shall we do?” He said, “Do not be afraid, for those who are with us are more than those who are with them.” Then Elisha prayed and said, “O LORD, please 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 all around Elisha. And when the Syrians came down against him, Elisha prayed to the LORD and said, “Please strike this people with blindness.” So he struck them with blindness in accordance with the prayer of Elisha.
