Proverbs 23:9-18

Speak not in the ears of a [self-confident] fool, for he will despise the [godly] Wisdom of your words. [Isa. 32:6.] Remove not the ancient landmark and enter not into the fields of the fatherless, [Deut. 19:14; 27:17; Prov. 22:28.] For their Redeemer is mighty; He will plead their cause against you. Apply your mind to instruction and correction and your ears to words of knowledge. Withhold not discipline from the child; for if you strike and punish him with the [reedlike] rod, he will not die. You shall whip him with the rod and deliver his life from Sheol (Hades, the place of the dead). My son, if your heart is wise, my heart will be glad, even mine; Yes, my heart will rejoice when your lips speak right things. Let not your heart envy sinners, but continue in the reverent and worshipful fear of the Lord all the day long. For surely there is a latter end [a future and a reward], and your hope and expectation shall not be cut off.
