Biblical: Son of Adam בן אדם. e.i. Cain Abel and Seth. Or any male person of the human race. גבר, a man when dealing with his masculinity. איש , a man with God given responsibilities eg his wife or job.
DaveSmith, in the Bible, גבר is pronounced gibor, often translated as mighty man. So I might say that in the Bible, gibor is a man off to battle.
A man dealing with his masculinity doesn’t sound like a very biblical theme to me.
