Seest thou a man wise in his own conceit? There is more hope of a fool than of him (Proverbs 26:12).

He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered. (Proverbs 28:26)

As a man thinks in his heart, so is he. [Proverbs 23:7]

The ear that heareth the reproof of life abideth among the wise (Proverbs 15:31).

A wise man has great power, and a man of knowledge increases strength. [Proverbs 24:5]

The fruit of the righteous is a tree of life; and he that winneth souls is wise (Proverbs 11:30).
