Watch out for fools (v. 7)! Wisdom builds but folly destroys (v. 1), and the tent of the godly is stronger than the house of the wicked (v. 11). When you obey the Word of God, you build on a solid foundation (Matt. 7:21–27).
Watch out for fools! Their speech can tear you down (v. 7), for their words are like a rod that hurts (v. 3). You cannot trust what they say (v. 8); they mock at sin (v. 9); and they rage in their self-confidence (v. 16). Be sure to watch out for their temper (vv. 17, 29); it can get you and them into trouble.
When you fear the Lord, your walk will be marked by uprightness (vv. 2, 16), confidence (v. 26), and protection (v. 27). The fear of the Lord is better than the folly of fools.
