John Calvin's Bible Commentary
Obadiah 1:8
We must now notice what the Prophet says, Shall I not in that day destroy the wise from Edom? Though men be in many respects blind, whom God guides not by his Spirit, and on whom he shines not with his word, yet the worst blindness is, when men become inebriated with the false conceit of wisdom. When therefore any one thinks himself endued with understanding, so that he can perceive whatever is needful, and that he cannot be circumvented, his wisdom is insanity and extreme madness: it would indeed be better for us to be idiots and fools than to be thus inebriated. Since then the wise of this world are insane, the Lord declares that they will have no wisdom when the time of trial comes. God indeed permits the ungodly for a long time to felicitate themselves on account of their own acumen and counsels, as he suffered the Idumeans to go on prosperously. And there are also many at this day who felicitate themselves on their successes, and almost adore their own cunning. Who indeed can persuade the Venetians that there is anywhere consummate wisdom but among themselves, by which, forsooth, they surpass all others in deception? For no other reason do they, amidst many agitations, retain their own position, except that they seem to see farther into what is for their own advantages; nay, that kings in general stand, and continue safe amidst so many shakings, this they ascribe to their own wisdom: “Except I had looked well in this respect to my own affairs, except I had anticipated danger, and except I had foreseen it, it would have been all over as to my condition.” Thus they think within themselves: but the Lord at length infatuates them, that it may be evident, that this was not formerly said in vain to the Idumeans, Shall I not in that day, saith Jehovah, etc. and it was emphatically added, in that day: for the Prophet means, that it was no wonder that the Idumeans had been hitherto wary and adopted the best counsel; for it was not the Lord’s purpose to deprive them of wisdom; but when the suitable time of vengeance came, he instantly took away whatever prudence there was in them; for it is indeed in God’s hand to take away whatever there is either of understanding or of acuteness in men.
But we are warned by these words, that if we excel in understanding, we are not to abuse this singular gift of God, as we see the case to be with the ungodly, who turn to cunning whatever wisdom the Lord has bestowed on them. There is hardly one in a hundred to be found, who does not seek to be crafty and deceitful, if he excels in understanding. This is a very wretched thing. What a great treasure is wisdom? Yet we see that the world perverts this excellent gift of God; the more reason there is for us to labor, that our wisdom should be founded in true simplicity. This is one thing. Then we must also beware of trusting in our own understanding, and of despising our enemies, and of thinking that we can ward off any evil that may impend over us; but let us ever seek from the Lord, that we may be favored at all times with the spirit of wisdom, that it may guide us to the end of life: for he can at any moment take from us whatever he has given us, and thus expose us to shame and reproach.
When he says, from mount Esau, he means mount Seir, as I have already reminded you. But he meant to point out their whole country; for they were almost surrounded by mountains, and dwelt, as it is well known, in that Arabia which is called Patraea. It follows —
