4 But now in that which follows, “they have made Jerusalem for a keeping of apples;” even the Church herself is rightly understood under this name, even the free Jerusalem our mother, concerning whom has been written, “many more are the sons of the forsaken, than of her that has the husband.” The expression, “for a keeping of apples,” I think must be understood of the desertion which the wasting of persecution has effected: that is, like a keeping of apples; for the keeping of apples is abandoned, when the apples have passed away. And certes when through the persecuting Gentiles the Church seemed to be forsaken, unto the celestial table, like as it were many and exceeding sweet apples from the garden of the Lord, the spirits of the martyrs did pass away.
5. “They have made,” he says, “the dead bodies of Your servants morsels for the fowls of heaven, the fleshes of Your saints for the beasts of the earth”. The expression, “dead bodies,” has been repeated in “fleshes:” and the expression, “of Your servants,” has been repeated in, “of Your saints.” This only has been varied, “to the fowls of heaven, and to the beasts of the earth.” Better have they interpreted who have written “dead,” than as some have it, “mortal.” For “dead” is only said of those that have died; but mortal is a term applied even to living bodies. When then, as I have said, to their Husbandman the spirits of martyrs like apples had passed away, their dead bodies and their fleshes they set before the fowls of heaven and the beasts of the earth: as if any part of them could be lost to the resurrection, whereas out of the hidden recesses of the natural world He will renew the whole, by whom even our hairs have been numbered.
6. “They have poured forth their blood like water,” that is, abundantly and wantonly, “in the circuit of Jerusalem”. If we herein understand the earthly city Jerusalem, we perceive the shedding of their blood in the circuit thereof, whom the enemy could find outside the walls. But if we understand it of that Jerusalem, concerning whom has been said, “many more are the sons of her that was forsaken, than of her that has the husband,” the circuit thereof is throughout the universal earth. For in that lesson of the Prophet, wherein is written, “many more are the sons of her that was forsaken, than of her that has the husband:” a little after unto the same is said, “and He that has delivered you, shall be called the God of Israel of the universal earth.” The circuit then of this Jerusalem in this Psalm must be understood as follows: so far as at that time the Church had been expanded, bearing fruit, and growing in the universal world, when in every part thereof persecution was raging, and was making havoc of the Martyrs, whose blood was being shed like water, to the great gain of the celestial treasuries. But as to that which has been added, “and there was no one to bury:” it either ought not to seem to be an incredible thing that there should have been so great a panic in some places, that not any buriers at all of holy bodies came forward: or certes that unburied corpses in many places might lie long time, until being by the religious in a manner stolen they were buried.
7. “We have become,” he says, “a reproach to our neighbours”. Therefore precious not in the sight of men, from whom this reproach was, but “precious in the sight of the Lord is the death of His saints.” “A scoffing and derision:” or, as some have interpreted it, “a mockery to them that are in our circuit.” It is a repetition of the former sentence. For that which above has been called, “a reproach,” the same has been repeated in, “a scoffing and derision:” and that which above has been said in, “to our neighbours,” the same has been repeated in, “to them that are in our circuit.” Moreover, in reference to the earthly Jerusalem, the neighbours, and those in the circuit of that nation, are certainly understood to be other nations. But in reference to the free Jerusalem our mother, there are neighbours even in the circuit of her, among whom, being her enemies, the Church dwells in the circuit of the round world.
