Proverbs 20:20–30 (NKJV)
20 Whoever curses his father or his mother, His lamp will be put out in deep darkness. 21 An inheritance gained hastily at the beginning Will not be blessed at the end. 22 Do not say, “I will recompense evil”; Wait for the Lord, and He will save you. 23 Diverse weights are an abomination to the Lord, And dishonest scales are not good. 24 A man’s steps are of the Lord; How then can a man understand his own way? 25 It is a snare for a man to devote rashly something as holy, And afterward to reconsider his vows. 26 A wise king sifts out the wicked, And brings the threshing wheel over them. 27 The spirit of a man is the lamp of the Lord, Searching all the inner depths of his heart. 28 Mercy and truth preserve the king, And by lovingkindness he upholds his throne. 29 The glory of young men is their strength, And the splendor of old men is their gray head. 30 Blows that hurt cleanse away evil, As do stripes the inner depths of the heart.
A son who rebels or curses his parents will be killed. Hastily gained wealth will run out. Evil will be recompensed. Vows made rashly may later be a snare. Judgement of the wicked comes through the king. Blows and stripes cleanse away evil. In verses 24 and 27 discuss the omniscience of God and His desire to direct our lives into blessing. In the middle of this lesson, the writer mentions that the glory of young men is their strength, and the splendor of an old man is their gray head. These lessons primarily relate to crime and punishment, sowing and reaping. If you do the crime, you do the time; if you play, you pay! All these cliches from years of observation of human nature and its consequences boil down to one thought process: if you do evil, their will be results that may not be pleasant, and could be downright crushing. Therefore, the greatest part of the lesson is to live well, act right, and behave wisely.
