Albert Barnes Commentary Job 18:19

"He shall have neither son nor son`s son among his people, Nor any remaining where he sojourned." — Job 18:19 (ASV)

He shall neither have son ...- All his family shall be cut off. He shall have no one to perpetuate his name or remembrance. All this Job could not help applying to himself, as it was doubtless intended he should. The facts in his case were just such as were supposed in these proverbs about the wicked; and hence, his friends could not but conclude that he was a wicked man; and hence, his friends could not but conclude that he was a wicked man; and hence, too, since these were undisputed maxims, Job felt so much embarrassment in answering them.
