Jamieson, Fausset & Brown, on 2Kgs 6:17

“And Eliseus prayed, and said: Lord, open his eyes, that he may see. And the Lord opened the eyes of the servant, and he saw: and behold the mountain was full of horses, and chariots of fire round about Eliseus.”

“Elisha prayed, and said, Lord, I pray thee, open his eyes, that he may see--The invisible guard of angels that encompass and defend us (Psa 34:7). The opening of the eyes, which Elisha prayed for, were those of the Spirit, not of the body--the eye of faith sees the reality of the divine presence and protection where all is vacancy or darkness to the ordinary eye. The horses and chariots were symbols of the divine power (see on Kg2 2:12); and their fiery nature denoted their supernatural origin; for fire, the most ethereal of earthly elements, is the most appropriate symbol of the Godhead [KEIL].”
