1 Corinthians 16:2-4

AUV(i) 2 On every first day of the week [i.e., at the regular Sunday assembly] each one of you should set aside and store up [money] in proportion to your income, so that no collections will have to be taken when I come. 3 Then when I arrive, I will send letters with the men you appoint to take the gift to Jerusalem. 4 And if it seems suitable for me to go also, they can go with me.
