1 Corinthians 16:1-3

Now about the collection for the Lord’s people: Do what I told the Galatian churches to do. 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. Then, when I arrive, I will give letters of introduction to the men you approve and send them with your gift to Jerusalem.
