8 “The swords of the enemy have failed at the end”. Not enemies in the plural, but this enemy in the singular. Now what enemy's swords have failed but the devil's? Now these are understood to be various erroneous opinions, whereby as with swords he destroys souls. In overcoming these swords, and in bringing them to failure, that sword is employed, of which it is said in the seventh Psalm, “If you be not converted, He will brandish His sword.” And perhaps this is the end, against which the swords of the enemy fail; since up to it they are of some avail. Now it works secretly, but in the last judgment it will be brandished openly. By it the cities are destroyed. For so it follows, “The swords of the enemy have failed at the end: and You have destroyed the cities.” Cities indeed wherein the devil rules, where crafty and deceitful counsels hold, as it were, the place of a court, on which supremacy attend as officers and ministers the services of all the members, the eyes for curiosity, the ears for lasciviousness, or for whatsoever else is gladly listened to that bears on evil, the hands for rapine or any other violence or pollution soever, and all the other members after this manner serving the tyrannical supremacy, that is, perverse counsels. Of this city the commonalty, as it were, are all soft affections and disturbing emotions of the mind, stirring up daily seditions in a man. So then where a king, where a court, where ministers, where commonalty are found, there is a city. Now again would such things be in bad cities, unless they were first in individual men, who are, as it were, the elements and seeds of cities. These cities He destroys, when on the prince being shut out thence, of whom it was said, “The prince of this world” has been “cast out,” these kingdoms are wasted by the word of truth, evil counsels are laid to sleep, vile affections tamed, the ministries of the members and senses taken captive, and transferred to the service of righteousness and good works: that as the Apostle says, “Sin should no more reign in” our “mortal body,” and so forth. Then is the soul at peace, and the man is disposed to receive rest and blessedness. “Their memorial has perished with uproar:” with the uproar, that is, of the ungodly. But it is said, “with uproar,” either because when ungodliness is overturned, there is uproar made: for none passes to the highest place, where there is the deepest silence, but he who with much uproar shall first have warred with his own vices: or “with uproar,” is said, that the memory of the ungodly should perish in the perishing even of the very uproar, in which ungodliness riots.
9. “And the Lord abides for ever”. “Wherefore” then “have the heathen raged, and the people imagined vain things against the Lord, and against His anointed:” for “the Lord abides for ever. He has prepared His seat in judgment, and He shall judge the world in equity.” He prepared His seat when He was judged. For by that patience Man purchased heaven, and God in Man profited believers. And this is the Son's hidden judgment. But seeing He is also to come openly and in the sight of all to judge the quick and the dead, He has prepared His seat in the hidden judgment: and He shall also openly “judge the world in equity:” that is, He shall distribute gifts proportioned to desert, setting the sheep on His right hand, and the goats on His left. “He shall judge the people with justice”. This is the same as was said above, “He shall judge the world in equity.” Not as men judge who see not the heart, by whom very often worse men are acquitted than are condemned: but “in equity” and “with justice” shall the Lord judge, “conscience bearing witness, and thoughts accusing, or else excusing.”
10. “And the Lord has become a refuge to the poor”. Whatsoever be the persecutions of that enemy, who has been turned behind, what harm shall he do to them whose refuge the Lord has become? But this will be, if in this world, in which that one has an office of power, they shall choose to be poor, by loving nothing which either here leaves a man while he lives and loves, or is left by him when he dies. For to such a poor man has the Lord become a refuge, “an Helper in due season, in tribulation.” Lo, He makes poor, for “He scourges every son whom He receives.” For what “an Helper in due season” is, he explained by adding “in tribulation.” For the soul is not turned to God, save when it is turned away from this world: nor is it more seasonably turned away from this world, except toils and pains be mingled with its trifling and hurtful and destructive pleasures.
11. “And let them who know Your Name, hope in You”, when they shall have ceased hoping in wealth, and in the other enticements of this world. For the soul indeed that seeks where to fix her hope, when she is torn away from this world, the knowledge of God's Name seasonably receives. For the mere Name of God has now been published everywhere: but the knowledge of the name is, when He is known whose name it is. For the name is not a name for its own sake, but for that which it signifies. Now it has been said, “The Lord is His Name.” Wherefore whoso willingly submits himself to God as His servant, has known this name. “And let them who know Your Name hope in You”. Again, the Lord says to Moses, “I am That I am; and You shall say to the children of Israel, I Am, has sent me.” “Let them” then “who know Your Name, hope in You;” that they may not hope in those things which flow by in time's quick revolution, having nothing but “will be” and “has been.” For what in them is future, when it arrives, straightway becomes the past; it is awaited with eagerness, it is lost with pain. But in the nature of God nothing will be, as if it were not yet; or has been, as if it were no longer: but there is only that which is, and this is eternity. Let them cease then to hope in and love things temporal, and let them apply themselves to hope eternal, who know His name who said, “I am That I am;” and of whom it was said, “I Am has sent me.” “For You have not forsaken them that seek You, O Lord.” Whoso seek Him, seek no more things transient and perishable; “For no man can serve two masters.”
12. “Sing to the Lord, who dwells in Sion”, is said to them, whom the Lord forsakes not as they seek Him. He dwells in Sion, which is interpreted watching, and which bears the likeness of the Church that now is; as Jerusalem bears the likeness of the Church that is to come, that is, the city of Saints already enjoying life angelical; for Jerusalem is by interpretation the vision of peace. Now watching goes before vision, as this Church goes before that one which is promised, the city immortal and eternal. But in time it goes before, not in dignity: because more honourable is that whither we are striving to arrive, than what we practise, that we may attain to arrive; now we practise watching, that we may arrive at vision. But again this same Church which now is, unless the Lord inhabit her, the most earnest watching might run into any sort of error. And to this Church it was said, “For the temple of God is holy, which temple you are:” again, “that Christ may dwell in the inner man in your hearts by faith.” It is enjoined us then, that we sing to the Lord who dwells in Sion, that with one accord we praise the Lord, the Inhabitant of the Church. “Show forth His wonders among the heathen.” It has both been done, and will not cease to be done.
