The apostle here reproves ambition, and an arrogant magisterial tongue; and shows the duty and advantage of bridling it because of its power to do mischief. Those who profess religion ought especially to govern their tongues (Jam 3:1-12). True wisdom makes men meek, and avoiders of strife and envy: and hereby it may easily be distinguished from a wisdom that is earthly and hypocritical (Jam 3:13 to the end).
