Job 41:18

Others believe that here he alludes to the fact that sneezing has the power to purify the brain; therefore, [the devil] transfigures himself into light, and even pretends to be able to purify. So [faithless] Gentiles and wizards use the devil's power in certain rites of purification, pretending that they have the power of the light, whereas they are entirely full of filth.

His sneezing is the splendour of fire. And his eyes as the eyelids of the morning. 56. This passage we expound the better, if we first enquire, how sneezing is produced. For in sneezing the breath rises up from the breast, and when it finds no pores open for its escape, it touches the brain, and, passing out condensed through the nostrils, it shakes at once all the head. In this body therefore of Leviathan, that is, in either malignant spirits, or reprobate men, who have adhered to him through resemblance in their guilt, a breath rises, as it were, from the breast, when pride exalts itself through the power of the present world. And it finds as it were no pores for escape; because in this raising up of itself against the just, it is kept, by God's provision, from prevailing as much as it desires. But it ascends and touches and shakes the brain, because the collected pride of Satan strikes the sense more closely at the end of the world, and disturbs the head, when it excites more vehemently the author himself of malignant spirits to the persecution of the faithful, by him who is called Antichrist. Then does the condensed breath come forth through his nostrils, because the iniquity of his pride is fully set forth by the open blasts of his malice. Because therefore sneezing especially shakes the head, that last commotion of this Leviathan, with which he enters into that accursed man, and by him rules over the reprobate, is called his 'sneezing.' And he rouses himself at that time with such power, as to confound, if possible, even the Elect members of the Lord: he makes use of such signs and prodigies, as to seem to glitter with the power of miracles, as if with a kind of light of fire. Because his head then strives, when aroused, to shine forth with miracles, his sneezing is rightly called the splendour of fire. For in rousing himself to persecute the just, he shines forth before the eyes of the reprobate with mighty signs. And because the wise ones of the world adhere to his tyranny, and he exercises by their advice every evil which he attempts, it is rightly subjoined, And his eyes as the eyelids of the morning. 57. For by his 'eyes,' which are fixed in his head, and serve the purpose of sight, his counsellors are not improperly designated, who, when they foresee in their perverse machinations in what manner what things are to be done, point out to his evil…
