I Corinthians 16:1-6 NKJV

Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also: On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come. And when I come, whomever you approve by your letters I will send to bear your gift to Jerusalem. But if it is fitting that I go also, they will go with me. Now I will come to you when I pass through Macedonia (for I am passing through Macedonia). And it may be that I will remain, or even spend the winter with you, that you may send me on my journey, wherever I go.
