2 Kings 6:17

open his eyes To the servant there was need of a more manifest vision, and for this Elisha prays, and God vouchsafes to grant it, that the servant may become as confident as his master. It is not that the troops may be gathered that Elisha prays, they are there already, but that the servant may have a seeing eye bestowed upon him to discern how well he and his master are protected.

the mountain was fullof horses and chariots of fire Just as in chapter 2 Kings 2:11 we read of appearances so described. It is not necessary that we suppose the vision to have been of literal horses and chariots. The heavenly host was seen encamped about God's servant in such wise as to disperse all fear.

round about Elisha The enemy compassed the town all round, but there was an inner circle filled by God's army. Dothan stood on an eminence and so the summit could thus be encircled, and the barrier against the Syrians appear complete.
