Job 41:22

"In its neck" means in arrogant self-estimation; "its strength abides," because it does not stand still but always overestimates itself. The souls that advance with a high neck (as is confirmed by Isaiah) are [like the devil's] neck, because they have the power to deceive. But such a power is vain; indeed, the weakness that my Savior and Lord assumed for me, which is called the weakness of God, completely defeated that power.

In his neck will remain strength. 1. Because we bear about us a body from this world, let us consider the end of the universe, from the part of it in which we ourselves are [al. 'which we are']. For we learn more quickly of what kind is the end of the world, if we carefully consider that which we bear about us from the world. For our age flourishes more vigorously in our youthful years, but in the time of old age it is shrivelled up by increasing diseases, and while its existence is extended to greater length, instead of dying it daily fails every moment of its life. So also as the duration of the world increases in years, it suffers under increasing evils, and it feels the loss of its health, as it obtains increase of age. For its tribulations increase together with its years, and it endures with greater weakness the losses of life, the more it lasts on, as it were, to a more advanced age. For the ancient enemy is let loose against it with all his strength, who, although he has already perished, as having lost the happiness of his heavenly condition, is yet at that time more fully extinguished, when he is deprived of his permission to tempt, and is fast bound in eternal fires. He is about, accordingly, to assail the ends of the world with severer temptations, because he becomes more raging in his cruelty, the nearer he perceives himself to punishment. For he considers that he is just about to lose his privilege of most fatal liberty. And the more he is confined by the shortness of the time, the more does he spread forth with multiplicity of cruelty, as is said of him by the voice of the angel to John; Woe to the earth, and to the sea, because the devil is come down unto you, having great wrath, knowing that he hath but a short time. [Rev. 12, 12] He then spreads himself forth into the fury of great wrath, in order that he, who could not remain in his state of happiness, may not fall into the pit of his damnation with a few only. He then searches out with greater craft whatever power of iniquity he has gotten, he then exalts more highly his neck of pride, and by means of that accursed man whom he wears, displays for the purpose of evil, all the temporal power he possesses. Whence also it is now rightly said by the Divine voice; In his neck will remain strength. 2. For what is designated by the 'neck' of that Leviathan, except the stretching out of his…
