1. Moyses L⟨e⟩x intelligitur. Virga crux Christi. Moyses ad Aegyptum veniens, fratres charissimi, defert et virgam, qua castigat et verberat Aegyptum decem plagis. Moyses Lex intelligitur, quae data est huic mundo, ut eum decem plagis, id est decem mandatis quae in Decalogo continentur, corripiat et emendet. Quod autem Lex Moyses intelligi possit, Dominus in Evangelio dixit: Habent Moysen et Prophetas (Luc. XVI, 29); id est, Legem et Prophetas. Virga vero per quam Aegyptus subjicitur et Pharao superatur, crucis Christi imaginem praeferebat, per quam mundus hic vincitur, et princeps hujus mundi cum principatibus et potestatibus triumphatur. Quod autem virga projecta fit draco vel serpens, et devorat Aegyptiorum serpentes; serpens pro sapientia ponitur, sicut scriptum est: Estote prudentes, sicut serpentes (Matth. X, 16). Idcirco virga Moysi, id est, crux Christi, posteaquam ad terras descendit, id est, posteaquam ad credulitatem et fidem hominum venit, conversa est in sapientiam, et tantam sapientiam quae omnem Aegyptiorum, id est, hujus mundi sapientiam devoraret.
1. Moses is understood as the Law. The rod is the cross of Christ. Moses, coming to Egypt, dearest brethren, brings also a rod, with which he chastises and strikes Egypt with ten plagues. Moses is understood as the Law, which was given to this world, so that it might rebuke and correct it with ten plagues, that is, with the ten commandments which are contained in the Decalogue. That Moses can be understood as the Law, the Lord said in the Gospel: They have Moses and the Prophets (Luke 16:29); that is, the Law and the Prophets. The rod, moreover, by which Egypt is subdued and Pharaoh overcome, bore the image of the cross of Christ, by which this world is conquered, and the prince of this world with the principalities and powers is triumphed over. As for the fact that the rod, when thrown down, becomes a dragon or serpent, and devours the serpents of the Egyptians: the serpent is put for wisdom, as it is written: Be prudent, as serpents (Matt. 10:16). Therefore the rod of Moses, that is, the cross of Christ, after it came down to earth, that is, after it came to the belief and faith of men, was turned into wisdom, and into so great a wisdom that it devoured all the wisdom of the Egyptians, that is, of this world.
2. Plagae Aegyptiorum. Sanguis. Ranae Cynomyia. Mors animalium. Ulcera et vesicae. Tonitrua. Locustae. Tenebrae. Mors primogenitorum. Quod vero aquae fluminis vertuntur in sanguinem, satis convenienter aptatur ut fluvius cui Hebraeorum parvulos crudeli nece tradiderant, auctoribus sceleris poculum sanguinis redderet, et cruorem polluti gurgitis, quem parricidali caede maculaverant, potando sentirent. Secunda vero plaga in qua inducuntur ranae, indicari figuraliter arbitror carmina poetarum; qui inani quadam et inflata modulatione, velut ranarum sonis et cantibus, mundo huic deceptionis fabulas intulerunt. Ad nihil enim animal illud utile est, nisi quod sonum vocis improbis et importunis clamoribus reddit. Post hoc sciniphes producuntur. Hoc animal pennis quidem suspenditur per aera volitans; sed adeo subtile est et minutum, ut oculi visum, nisi acute cernentis, eludat: corpus tamen cui insederit, acerbissimo terebrat stimulo; ita ut quem volantem videre quis non valet, sentiat stimulantem. Hoc ergo animalis genus dignissime puto arti philosophiae vel haereticorum calliditati comparari, quae minutis et subtilibus verborum stimulis animas terebrat, et tanta calliditate circumvenit, ut deceptus quisque nec videat, nec intelligat unde deceptus sit. Quarto quoque in loco cynomyia, id est, musca canina inducitur, quae Cynicorum sectae merito comparatur, qui ad reliquas deceptionis suae improbitates, etiam voluptatem et libidinem summum praedicant bonum. Quoniam igitur per haec singula prius deceptus est mundus, adveniens sermo et Lex Dei hujuscemodi eum correptionibus arguit, ut ex qualitate poenarum qualitates proprii agnoscat erroris. Quinto in loco animalium nece vel pecudum Aegyptus v⟨e⟩rberatur. Vecordia in hoc arguitur stultitiaque mortalium, qui tanquam irrationabilia pecora cultum et vocabulum Dei imposuerunt figuris non solum hominum, sed et pecorum. Unde justo judicio factum est, ut in quibus cultum credebant inesse divinum, in his viderent miseranda supplicia. Ulcera post haec et vesicae cum fervore, sexto in verbere producuntur: et videtur mihi, quod in ulceribus arguatur dolosa et prurulenta malitia, in ve⟨s⟩icis tumens et inflata superbia, in fervore irae ac furoris insania. Huc usque per errorum suorum figuras mundo supplicia temperantur. Post haec vero verbera veniunt de supernis voces et tonitrua, et grando, et ignis discurrens
2. The plagues of the Egyptians. Blood. Frogs Dog-fly. Death of animals. Ulcers and blisters. Thunders. Locusts. Darkness. Death of the first-born. That the waters of the river are turned into blood is fittingly enough adapted so that the river, to which they had delivered the little ones of the Hebrews by a cruel death, might give back to the authors of the crime a cup of blood, and that they might feel, by drinking it, the gore of the polluted stream which they had stained with parricidal slaughter. The second plague, in which frogs are brought in, I judge to signify figuratively the songs of the poets, who with a certain empty and inflated melody, as with the sounds and songs of frogs, brought into this world fables of deception. For that animal is useful for nothing, except that it gives forth the sound of its voice in shameless and troublesome clamours. After this gnats are brought forth. This creature is indeed held up on wings, flying through the air; but it is so fine and minute that it escapes the sight of the eye, unless of one who looks keenly: yet the body on which it settles it pierces with a most bitter sting; so that one who cannot see it flying feels it stinging. This kind of creature, therefore, I think is most fittingly compared to the art of philosophy or to the cunning of the heretics, which pierces souls with minute and subtle stings of words, and circumvents with such cunning that the one deceived neither sees nor understands whence he has been deceived. In the fourth place, too, the cynomyia, that is, the dog-fly, is brought in, which is deservedly compared to the sect of the Cynics, who, in addition to the other shameless features of their deception, proclaim even pleasure and lust to be the highest good. Since, therefore, the world was first deceived by each of these things, the word and Law of God, coming, convicts it by corrections of this kind, so that from the quality of the punishments it may recognize the qualities of its own error. In the fifth place Egypt is struck by the slaughter of animals or cattle. In this is convicted the madness and folly of mortals, who like irrational cattle have imposed the worship and name of God upon the figures not only of men but also of cattle. Hence it came about by just judgement that in those things in which they believed divine worship to reside, they should see pitiable punishments. Ulcers and blisters with burning heat are brought forth after these in the sixth stroke: and it seems to me that in the ulcers is convicted deceitful and itching malice, in the blisters swelling and inflated pride, in the burning heat the madness of wrath and fury. Up to this point punishments are tempered for the world through the figures of its own errors. After these strokes, however, there come from on high voices and thunders, and hail, and fire running
