1. The tongue of the wise (17-19, 22-23, 25)
People's wisdom is revealed in their words. The wise are honest and speak the truth even when it is costly and dangerous to do so (17). Their words lead to healing and impart truth that leads to eternal life (18, 19). They fear God and do not lie; they are trustworthy (22). Instead of speaking as an authority, their prudence in choosing their words humbly protects them from folly (23). Their words have power to free people from anxiety and to cheer their hearts (25). We must examine our words and repent our foolish talk and ask God for a spirit of wisdom to choose our words.
2. The way of the righteous (15-16, 20-21, 24, 26-28)
The wise are humble enough to listen to advice and overlook insults (15-16). The wise promote and enjoy peace; they don't create dissension or go looking for trouble (20-21). The wise are diligent and fill leadership positions (24). They choose their friends carefully and avoid bad company (26). They don't rush, but carefully consume their gains (27). Through their careful decisions, the wise lead a righteous life that leads to eternal life. To follow the way of the righteous is truly wise.
