'Men' in the Bible

namely, a man of unquestionable integrity, the husband of one wife, having children who believe, not accused of being immoral or rebellious.

For there are many rebellious men who are empty talkers [just windbags] and deceivers; especially those of the circumcision [those Jews who insist that Gentile believers must be circumcised and keep the Law in order to be saved].

not paying attention to Jewish myths and the commandments and rules of men who turn their backs on the truth.

Older men are to be temperate, dignified, sensible, sound in faith, in love, in steadfastness [Christlike in character].

In a similar way urge the young men to be sensible and self-controlled and to behave wisely [taking life seriously].
