Job 3:8

May this one curse her, who will curse the day. That is to say, the Lord, who curses lovers of carnal pleasures.

May this night or day of detestation become what the horrible and cruel dragon that is led from the sea to the earth deserves. Indeed the Hebrew and Syrian tradition interpret Leviathan to be the one about which David says, "There is that dragon that you have made to delude him." Even though the dragon seems to represent, above all, a figure of spiritual iniquity, it nonetheless, after getting out and being cast onto earth, is said to possess the ability to cause many massacres of people and animals. Thus, with good reason, the curses of all must be gathered against it.

MORAL INTERPRETATION. Let them curse it that curse the day. As if he said in plain words; 'Let them strike the darkness of this night by truly repenting, who henceforth despise and tread upon the light of worldly prosperity.' For if we take 'the day,' for the gladness of delight, of this 'night' it is rightly said, Let them curse it that curse the day. In that, indeed, they do truly chastise the misdeeds committed with the visitations of penance, who are henceforth carried away by no sense of delight after deceitful goods. For of those whom other mischievous practices still delight, it is all false whereinsoever they are seen to bewail one set they have been guilty of. But if, as we have said above, we understand thereby the crafty suggestion of our old enemy, those are to be understood to curse the 'night,' that curse the 'day,' in that surely they all really punish their past sins, who in the mere flattering suggestion itself detect the snares of the malicious deceiver. Who are ready to rouse up Leviathan. For all they that with the spirit tread under foot the things which are of the world, and with a perfect bent of the mind desire the things that belong to God, rouse up Leviathan against themselves, in that they inflame his malice, by the incitements of their life and conduct. For those that are subject to his will, are as it were held in possession by him with an undisturbed light, and their tyrannizing king, as it were, enjoys a kind of security, while he rules their hearts with a power unshaken, but when the spirit of each man is quickened again to the longing after his Creator; when he gives over the sloth of negligence, and kindles the frost of former insensibility with the fire of holy love; when he calls to mind his innate freedom, and blushes that his enemy should keep him as his slave; because that enemy marks that he is himself contemned, and sees that the ways of God are laid hold of, he is stung that his captive struggles against him, and is at once fired with jealousy, at once pressed to the conflict, at once raises himself to urge countless temptations against the soul that withstands him, and stimulates himself in all the arts of mangling, that launching the darts of temptation he may pierce the heart, which he has long held with an undisputed title. For he slept, as it were, whilst he reposed at rest in the corrupt heart. But he is…
