Charles Ellicott Commentary 2 Kings 6:20

"And it came to pass, when they were come into Samaria, that Elisha said, Jehovah, open the eyes of these men, that they may see. And Jehovah opened their eyes, and they saw; and, behold, they were in the midst of Samaria." — 2 Kings 6:20 (ASV)

Behold, they were in the midst of Samaria.—Michaelis wonders how such a host could be led into the city without putting themselves on their guard. He overlooks the supernatural bewilderment which had fallen upon them. When their eyes were opened, and they realised their whereabouts, dismay and astonishment would paralyse their energies.
