1 Corinthians 16:2-4

16:2 On the first day of the week, each of you should set aside some income and save it to the extent that God has blessed you, so that a collection will not have to be made when I come. 16:3 Then, when I arrive, I will send those whom you approve with letters of explanation to carry your gift to Jerusalem. 16:4 And if it seems advisable that I should go also, they will go with me.
