Job 5:13 - Matthew Poole's English Annotations on the Holy Bible

The wise in their own craftiness; wicked men, who are wise to do evil, and wise in the opinion of the world, he not only deceiveth in their hopes and counsels, but turns them against themselves; as we see in Ahithophel, Haman, &c. The froward, or perverse, or wrestlers; such as wind and turn every way, as wrestlers do, and will leave no means untried to accomplish their counsels. Is carried headlong, i.e. is tumbled down and broken, and that by their own precipitation and haste. Their malice cannot have the patience to proceed wisely and leisurely against God's church and people, but makes them eager and venturous, and so to make more haste than good speed in their wicked designs.
