'Son' in the Bible

He shall neither have son nor nephew among his people, nor any remaining in his dwellings.

How much less man, that is a worm? and the son of man, which is a worm?

Then was kindled the wrath of Elihu the son of Barachel the Buzite, of the kindred of Ram: against Job was his wrath 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 very old; wherefore I was afraid, and durst not shew you mine opinion.

Thy wickedness may hurt a man as thou art; and thy righteousness may profit the son of man.
