Albert Barnes’ Commentary

And saith unto him, If thou be the Son of God, cast thyself down – The temptation here was, that he should at once avail himself of the protection of a promise of safety made to him, and thus demonstrate that he was the Messiah. If he was the true Messiah he had a certain assurance of protection, a promise that no harm could befall him; and thus, by so surprising a miracle, and such a clear proof of the divine interposition, he could at once establish his claim to the Messiahship. How much more easy would this be than to engage in a slow work of years to establish that claim; to encounter fatigue, and want, and poverty, and persecution, before that claim would be admitted! And where could be a more suitable place for thus at once demonstrating that he was the Son of God, than on this pinnacle of the temple, in the very midst of Jerusalem, and perhaps in the presence of thousands who would see the wonderful performance? The temptation, therefore, in this case was, that by thus establishing his claim he would avoid all the obloquy, persecution, and suffering which he must otherwise endure if he attempted to prove that he was the Son of God by a life of toil and privation.

It is written – That is, there is a passage of Scripture which promises special protection in such a case, and on which you may rely. The argument was not, perhaps, that this applied exclusively to the Messiah, but that, if applicable in any case, it would be in this; if anyone could plead this promise, assuredly he could who claimed to be the Son of God.

He shall give his angels charge concerning thee … – That is, they shall protect thee.

And in their hands they shall bear thee up – They shall sustain thee, or hold thee up, so that thou shalt not be endangered by the fall.

Lest at any time thou dash thy foot against a stone – This would be especially appropriate in such a case. The promise, as Satan applied it, was that he should not be injured by the stones lying at the bottom of the wall or in the valley below. The case, therefore, seemed to be one that was especially contemplated by the promise.
