He who ignores discipline despises himself, but whoever heeds correction gains understanding (Proverbs 15:32).

The proverbs of Solomon the son of David, king of Israel; / To know wisdom and instruction; to perceive the words of understanding; / To receive the instruction of wisdom, justice, and judgment, and equity; / To give subtilty to the simple, to the young man knowledge and discretion.

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]

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

Trust in the Lord with all thine heart; and lean not unto thine own understanding. (Proverbs 3:5)
