Job 21:21 - Joseph Benson’s Commentary on the Old and New Testaments

What pleasure hath he in his house after him? As for what befalls his children when he is dead, he concerns not himself; he is not affected with their felicity or misery, irreligion commonly making men unnatural. And therefore God punishes both him and his children while he lives, Job 21:19-20. Or, the meaning may be, what delight can he take in the thoughts of the glory and happiness of his posterity, when he finds he is dying a violent and untimely death? Thus, this is a further proof, that this man is neither happy in himself, nor with reference to his posterity. When the number, &c. When that number of months, which, by his constitution, and the course of nature, he might have lived, is diminished, and cut off by the hand of violence.
