On the first day of every week, each one of you should set aside a sum of money in keeping with your income, saving it up, so that when I come no collections will have to be made.
On the first [day] of each week, let each one of you [personally] put aside something and save it up as he has prospered [in proportion to what he is given], so that no collections will need to be taken after I come.
Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
Be on your guard; stand firm in the faith; be courageous; be strong.
Be alert and on your guard; stand firm in your faith (your conviction respecting man's relationship to God and divine things, keeping the trust and holy fervor born of faith and a part of it). Act like men and be courageous; grow in strength! [Ps. 31:24.]AMP
Watch ye, stand fast in the faith, quit you like men, be strong.
