2 Kings 6:18 - Joseph Benson’s Commentary on the Old and New Testaments

And when they came down to him Either in the city, into which they easily got admission, when they declared that the only end of their coming was to take Elisha; or rather, in the field, without the city, whither he went to meet them. Elisha prayed, and said, Smite this people, I pray thee, with blindness Not of the eyes, or, at least, not with total blindness, for in that case they could not have seen to have followed him; but rather with blindness of the mind, or imagination, which was rendered stupid and confused, or with that dimness and confusion in their sight, which prevented their distinguishing one object from another; the city of Dothan, for instance, from the city of Samaria. We have a similar case Genesis 19:11. Thus it happens to several men in their liquor, that though their eyes are open, and they can perceive the several objects which surround them, yet they cannot discern wherein they differ. And if we may suppose that the Syrian army was under the same αορασια, as the Greeks happily term such a degree of blindness or want of distinct vision, we need no more wonder that they readily accepted a guide who offered his service, than that a drunkard, after having lost his way, and found himself bewildered, should be thankful to any hand which should undertake to conduct him safe home Houbigant and Dodd.
