2 Kings 6:8-17 ESV
Once when the king of Syria was warring against Israel, he took counsel with his servants, saying, “At such and such a place shall be my camp.” But the man of God sent word to the king of Israel, “Beware that you do not pass this place, for the Syrians are going down there.” And the king of Israel sent to the place about which the man of God told him. Thus he used to warn him, so that he saved himself there more than once or twice.
And the mind of the king of Syria was greatly troubled because of this thing, and he called his servants and said to them, “Will you not show me who of us is for the king of Israel?” And one of his servants said, “None, my lord, O king; but Elisha, the prophet who is in Israel, tells the king of Israel the words that you speak in your bedroom.” 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.
