1 Corinthians 16:1-3 New Revised Standard Version (NRSV)
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.
