The Collection for the Saints

16 Now concerning the collection for the saints: you should follow the directions I gave to the churches of Galatia. ² On the first day of every week, each of you is to put aside and save whatever extra you earn, so that collections need not be taken when I come. ³ And when I arrive, I will send any whom you approve with letters to take your gift to Jerusalem.
