Jamieson, Fausset and Brown on Matthew 4:8

8. Again, the devil taketh him up--"conducteth him," as before.

into--or "unto"

an exceeding high mountain, and showeth him all the kingdoms of the world, and the glory of them--Luke (Lu 4:5) adds the important clause, "in a moment of time"; a clause which seems to furnish a key to the true meaning. That a scene was presented to our Lord's natural eye seems plainly expressed. But to limit this to the most extensive scene which the natural eye could take in, is to give a sense to the expression, "all the kingdoms of the world," quite violent. It remains, then, to gather from the expression, "in a moment of time"--which manifestly is intended to intimate some supernatural operation--that it was permitted to the tempter to extend preternaturally for a moment our Lord's range of vision, and throw a "glory" or glitter over the scene of vision: a thing not inconsistent with the analogy of other scriptural statements regarding the permitted operations of the wicked one. In this case, the "exceeding height" of the "mountain" from which this sight was beheld would favor the effect to be produced.
