 When I arrive, whomever you may approve, I will send with them letters to carry your gift to Jerusalem, and if it is fitting for me to go also. Now the Corinthians were to approve certain people to travel to Jerusalem with their offering. And verse 4 makes it clear that if it were fitting, and I understand Paul to be saying, if this offering is that which is honorable to the Lord, and it all works out in the schedule of me, I'll allow those people to travel with me as I take that to Jerusalem. That's what I see Paul saying here.
