Job 11:12 - Matthew Poole's English Annotations on the Holy Bible

Or, Yet, or But, vain or empty man (that foolish creature, that since the fall is void of all true wisdom and solid knowledge and judgment of the things of God) would be wise, i.e. pretends to be, and would be thought, wise, and able to pass a censure upon all God's ways and works. Or thus, But vain man is foolish, or without heart, i.e. without understanding, unable to judge aright of the ways and things of God. For a verb very like this and coming from the same root, signifies to have one's heart taken away, Song of Solomon 4:9. Though man be born; and man is born, i. e. he is by his birth such: this evil is now natural and hereditary, and therefore common to all men; and therefore it is not strange if Job partake of the common distemper. Like a wild ass's colt, i.e. ignorant, and dull, and stupid, as to the knowledge of Divine things, and withal heady and untractable; and therefore very incompetent to judge of these high affairs.
