This verb means to act like a man or show manly courage—to display strength, resolve, and bravery. Paul uses it in 1 Corinthians 16:13, urging believers to stand firm in faith, be courageous, and be strong. The Spanish sed-varones and German männlich-sein both invoke masculine ideals of courage and strength. This is not about gender but about the qualities traditionally associated with warriors—courage, endurance, and steadfastness in the face of opposition.
