John Gill's Exposition of the Whole Bible
Proverbs 14:18
The simple inherit folly,.... It is natural and hereditary to them, they are born like wild asses colts; the foolish sayings and proverbs, customs and practices, of their ancestors, though they have been demonstrated to be mere folly, yet these, their posterity, approve them; they love, like, and retain them as their patrimony, Job 11:12. Such are the foolish traditions, customs, principles, and doctrines, of the church of Rome, handed down from father to son; and because Popery is the religion they have been bred and brought up in, though so foolish and absurd, they will not relinquish it;
but the prudent are crowned with knowledge; natural, civil, and spiritual, especially the latter; evangelical knowledge, the knowledge of Christ, and of God in Christ, and of Gospel truths; they are honoured with an acquaintance with them; and they esteem the knowledge of these above all things else, and reckon all things else but loss and dung in comparison of them; they are as a crown unto them, and the knowledge of them is the way to the crown of life; yea, is itself life eternal, Philippians 3:8. Or, they "crown themselves with knowledge" p; they labour after it, pursue it with eagerness, follow on to know the Lord, and attain to a large share of it; surround, encompass, and lay hold upon it, and gird themselves about with this girdle of truth. Or, "they crown knowledge" q; do honour to that, by putting it in practice; by adding to it temperance, and every virtue, and by bringing others to it; and are an ornament to it in their lives and conversation; they adorn the doctrine of God their Saviour.
