I Coríntios 16:2

2 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.

2 On the first day of the week, let every one of you put by him in store, in measure as he has done well in business, so that it may not be necessary to get money together when I come.
