'Men' in the Bible

Be careful that you don't let anyone rob you through his philosophy and vain deceit, after the tradition of men, after the elements of the world, and not after Christ.

(all of which perish with use), according to the precepts and doctrines of men?

And whatever you do, work heartily, as for the Lord, and not for men,

and Jesus who is called Justus. These are my only fellow workers for the Kingdom of God who are of the circumcision, men who have been a comfort to me.
