Luke 19:44

This too which is added, namely, They shall not leave in thee one stone upon another, is now witnessed in the altered situation of the same city, which is now built in that place where Christ was crucified without the gate, whereas the former Jerusalem, as it is called, was rooted up from the very foundation. And the crime for which this punishment of overthrow was inflicted is added, Because thou knewest not the time of thy visitation.

That is, of my coming. For I came to visit and to save thee, which if thou hadst known and believed on Me, thou mightest have been reconciled to the Romans, and exempted from all danger, as did those who believed on Christ.

But our Jerusalem is also wept over, because after sin enemies surround it, (that is, wicked spirits,) and cast a trench round it to besiege it, and leave not a stone behind; especially when a man after long continency, after years of chastity, is overcome, and enticed by the blandishments of the flesh, has lost his fortitude and his modesty, and has committed fornication, they will not leave on him one stone upon another, according to Ezekiel, His former righteousness I will not remember. (Ezek 18:24.)

And therefore the siege which was shortly to come upon them He most expressly foretells, adding, For the days shall come upon thee, &c. But how these things were fulfilled we may gather from what is delivered to us by Josephus, who though he was a Jew, related each event as it toot place, in exact accordance with Christ's prophecies.

(Hom. 39. in Ev.) Or else; The evil spirits lay siege to the soul, as it goes forth from the body, for being seized with the love of the flesh, they caress it with delusive pleasures. They surround it with a trench, because bringing all its wickedness which it has committed before the eyes of its mind, they close confine it to the company of its own damnation, that being caught in the very extremity of life, it may see by what enemies it is blockaded, yet be unable to find any way of escape, because it can no longer do good works, since those which it might once have done it despised. On every side also they inclose the soul when its iniquities rise up before it, not only in deed but also in word and thought, that she who before in many ways greatly enlarged herself in wickedness, should now at the end be straitened every way in judgment. Then indeed the soul by the very condition of its guilt is laid prostrate on the ground, while its flesh which it believed to be its life is bid to return to dust. Then its children fall in death, when all unlawful thoughts which only proceed from it, are in the last punishment of life scattered abroad. These may also be signified by the stones. For the corrupt mind when to a corrupt thought it adds one more corrupt, places one stone upon another. But when the soul is led to its doom, the whole structure of its thoughts is rent asunder. But the wicked soul God ceases not to visit with His teaching, sometimes with the scourge and sometimes with a miracle; that the truth which it knew not it may hear, and though still despising it, may return pricked to the heart in sorrow, or overcome with mercies may be ashamed at the evil which it has done. But because it knows not the time of its visitation, at the end of life it is given over to its enemies, that with them it may be joined together in the bond of everlasting damnation.
