Verse 5. -
Except ye repent, ye shall all likewise perish. The words were indeed prophetic to the letter. Thousands of Jews perished in the last terrible war by the swords of the Roman legionaries, like the Galilaeans of ver. 1; not a few met their death in the capital among the ruins of the burning fallen houses. We know that Jerusalem in its entirety was destroyed, and the loss of life in the siege, and especially in its dread closing scenes, was simply incalculable. Within forty years all this happened.
13:1-5 Mention was made to Christ of the death of some Galileans. This tragical story is briefly related here, and is not met with in any historians. In Christ's reply he spoke of another event, which, like it, gave an instance of people taken away by sudden death. Towers, that are built for safety, often prove to be men's destruction. He cautioned his hearers not to blame great sufferers, as if they were therefore to be accounted great sinners. As no place or employment can secure from the stroke of death, we should consider the sudden removals of others as warnings to ourselves. On these accounts Christ founded a call to repentance. The same Jesus that bids us repent, for the kingdom of heaven is at hand, bids us repent, for otherwise we shall perish.
I tell you, nay,.... I affirm it, and you may depend upon it, they were not greater sinners than others: though such a melancholy accident befell them, not without the providence of God:
but except ye repent, ye shall all likewise perish; or perish in the same manner; that is, shall be buried under the ruins of the city and temple of Jerusalem, when one stone should not be left upon another; just as these eighteen men were buried under the ruins of the tower of Siloam, of which it was a pledge and emblem; and accordingly great numbers of them did perish in the temple, and were buried under the ruins of it (d).
