'Son' in the Bible

Oh that there were arbitration for a man with +God, as a son of man for his friend!

He hath neither son nor grandson among his people, nor any remaining in the places of his sojourn.

How much less man, a worm, and the son of man, a worm!

Then was kindled the anger of Elihu the son of Barachel, the Buzite, of the family of Ram: against Job was his anger kindled, because he justified himself rather than God;

And Elihu the son of Barachel the Buzite answered and said, I am young, and ye are aged; wherefore I was timid, and feared to shew you what I know.

Thy wickedness may affect a man as thou art, and thy righteousness a son of man.
