Adam Clarke on 1 Corinthians 7:30

They that weep, etc. - There will shortly be such a complete system of distress and confusion that private sorrows and private joys will be absorbed in the weightier and more oppressive public evils: yet, let every man still continue in his calling, let him buy, and sell, and traffic, as usual; though in a short time, either by the coming persecution or the levelling hand of death, he that had earthly property will be brought into the same circumstances with him who had none.
