Job 12:24

Who changeth the heart of the chief of the people of the earth, and deceiveth them, that they wander in vain where there is no way, they shall grope in the dark without any light, and He shall make them to stagger like a drunken man.

For 'the heart of the chief of the earth was changed,' when the chief priests and elders of the people in Judaea set themselves to withstand Him by their counsels, Whom they beforehand proclaimed, that He was to come. And when they strove to put out His Name by persecuting Him, being deceived by their own wickedness they vainly essayed to 'wander where there is no way,' because it was impossible that a 'way' could be open to their cruelty directed against the Creator of all things. They saw the miracles, they were made to fear by His power, but by a righteous judgment, light itself was made dark to them, in that whilst it came to heal the sound of mind, it blinded those that were puffed up. For in proportion as the light of miracles shone upon their faces, in the same degree were they darkened by the depth of their iniquity; and they that before His Incarnation seemed to 'walk right in the way,' after the Incarnation were made to 'stagger like a drunken man.' For a drunken man walks on that he may arrive at some place, yet he knows not what place he is making for. And so, when for the killing of the Lord, Judaea busied herself with the exertion of her evil intent, she toiled on, and knew not whither; because whereas she thought to destroy Him, Whom she had put to death, she multiplied the numbers of believers without any bounds, and 'staggered' when she was minded to fix her footing in the firmest way, in that wherein by her evil intent she thought to make an end, there being confuted, she increased His glory.

After he has shown there is strength, wisdom, and counsel in God, he finally shows that God is intelligent, understanding by this the knowledge which He has of hidden things, which seem above all to designate what is hidden in the heart. He shows that God knows these things by the fact that he works in the hearts of men, and thus he knows the hidden things of hearts like his own effects. So he says, "It is he who changes the heart of the leaders of the people of the land," with respect to their wills. As Proverbs says, "The heart of the king is in the hand of the Lord, who will incline it to whatever he wills." (21:1) Although God inclines the wills of all men, yet special mention is made of kings and princes because their wills carry more weight, for many follow their will. As to the intellect he adds, "he deceives them," which means certainly not that he leads them into falsity, but because he takes his light away from them, so that they may not know the truth, and clouds their reasoning power so that they cannot find suitable means to do the wicked deeds which they propose. So he then says, "so that they proceed in vain and along a trackless way," that is, so they proceed by ways which are unfitting, by means of which they cannot arrive at their end. One errs in acting in two ways: first, by ignorance, and regarding this he says, "they will grope in the darkness and not in the light," so that ignorance is designated by darkness and knowledge by light. Some grope in ignorance like blind men when they only consider what they can feel is right in front of them as if by touch. Some err in another way in actions because of their passions, by which their reason is bound in particular choices, so that they do not apply universal knowledge to action. As to this he adds, "and he will make them wander like drunkards," for their reason is so bound by passion that it is like a kind of drunkenness.
