Job 41:2

Hence it is that this very Mary of whom we speak lives, because He who owed nothing to death lay down for the human race. Hence it is that we daily return to life after our sins, because our Creator descended without guilt to our punishment. Behold, the ancient enemy has now lost the spoils he had begun to take from the human race; he has lost the victory of his supplanting. Daily sinners return to life; daily they are snatched from his jaws by the hand of the Redeemer. Wherefore it is also well said again to blessed Job by the voice of the Lord: "Or will you pierce his jaw with a bracelet?" Where a bracelet is placed, it constrains by encircling. What then is designated by the bracelet, if not the divine mercy embracing us? Which pierces the jaw of this Leviathan, when it still shows us the remedy of repentance after we have committed what it forbade. The Lord pierces the jaw of Leviathan with a bracelet, because by the ineffable power of His mercy He so opposes the malice of the ancient enemy that sometimes he loses even those whom he had already seized. And they fall as if from his mouth, who return to innocence after committing sins. For who, once seized by his mouth, would escape his jaw, if it had not been pierced? Did he not hold Peter in his mouth when he denied? Did he not hold David in his mouth when he plunged himself into such a pit of lust? But when each returned to life through repentance, this Leviathan in a certain way lost them as if through the hole in his jaw. Therefore through the hole in his jaw those were withdrawn from his mouth who returned through repenting after committing such great wickedness. But what man escapes the mouth of this Leviathan so as to commit no unlawful thing? But from this we know how much we are debtors to the Redeemer of the human race, who not only forbade us to go into the mouth of Leviathan, but also granted us to return from his mouth. He did not take away hope from the sinner, because He pierced his jaw to provide a way of escape, so that he who incautiously refused beforehand to beware lest he be bitten might at least flee after the bite. Therefore heavenly medicine meets us everywhere, because He both gave man precepts lest he sin, and yet gave remedies to the sinner lest he despair. Wherefore it must be most carefully guarded against that anyone be seized by the mouth of this Leviathan through delight…

Wilt thou put a ring into his nostrils? Or wilt thou bore through his jaw with a bracelet? 21. As stratagems are signified by 'nostrils,' so by a 'ring' is designated the omnipotence of Divine Power. For when it keeps us from being seized by temptations, it encircles around and holds firm in wondrous ways the snares of the ancient enemy. A ring is, therefore, put into his nostrils, when by the strength of heavenly protection drawn around us, his cunning is so restrained, as not to prevail so far against the weakness of man, as far as it secretly searches out its fatal arguments. But by the name 'ring' can be designated also the aid of the secret judgments, which is put into the nostrils of this Behemoth when he is restrained from his artful cruelty. Whence it is well said by the Prophet to the King of Babylon, when he is kept from injuring the Israelites; I will put a ring in thy nostrils. [Is. 37, 29] As if it were plainly said; Thou breathest hard with thoughts of guile; but from being unable to fulfil thy desires, thou bearest in thy nostrils the ring of My omnipotence, in order that when thou pantest more eagerly for the death of the righteous, thou mayest return unsatisfied from their life. But that which Holy Scripture calls in this place a 'ring,' it calls a 'sickle' by John in the Apocalypse. For he says, I looked, and behold a white cloud, and upon the cloud one sitting like the Son of Man, having on His head a golden crown, and in His hand a sharp sickle. [Rev. 14, 14] For the power of Divine judgment is called a 'ring,' because it binds on every side; but because in its cutting it embraces all things within it, it is marked out by the term 'sickle.' For whatever is cut by a sickle falls within it, in whatsoever direction it is turned. And because the power of the heavenly judgment cannot be in any way avoided, (for we are in truth within it, wherever we may endeavour to escape,) when the Judge Who is to come is represented, He is rightly said to hold a sickle. Because when He comes to meet all things in His might, He surrounds them in cutting them off. The Prophet saw that he was within the sickle of judgment, when he said, If I ascend into heaven. Thou art there: if I descend into hell, Thou art present. If I take my wings before the light, and dwell in the uttermost parts of the sea, even there also shall Thy hand lead me, and Thy right hand…
