5. Do they depend upon the politics of their counsellors? These shall fail them, v. 8. Edom had been famous for great statesmen, men of learning and experience, that sat at the help of government, and were masters of all the arts of management, that in all treaties used to outwit their neighbours; but now the counsellors have become fools, and the wise God makes them so: Shall I not in that day destroy the wise men out of Edom? As men they shall fall by the sword in common with others (Ps. xlix. 10), and their wisdom shall not secure them; as wise men they shall be infatuated in all their counsels; their best-laid designs shall be baffled, their measures broken, and those very projects by which they thought to establish themselves and the public interests shall be the ruin of both. Thus wisdom perishes from Teman, as it is in the parallel place, Jer. xlix. 7. This was, (1.) The just punishment of their folly in trusting to an arm of flesh: There is no understanding in them, v. 7. They have not sense to trust in a living God, and a God of truth, but put confidence in men that are frail, fickle, and false; and therefore God will destroy their understanding. Note, God will justly deny those understanding to keep out of the way of danger that will not use their understanding to keep out of the way of sin. He that will be foolish, let him be foolish still. (2.) It was the forerunner of their destruction. A nation is certainly marked for ruin when God hides the things that belong to its peace from the eyes of those that are entrusted with its counsels. Quos Deus vult perdere, eos dementat—God infatuates those whom he designs to destroy. Job xii. 17.
