1 Corinthians 9:1-6

Am I not free? Am I not an apostle? Have I not seen Jesus our Lord? Are you not my work in the Lord? If to others I am not an apostle, at least I am to you; for you are the seal of my apostleship in the Lord. My defense to those who examine me is this: Do we not have a right to eat and drink? Do we not have a right to take along a believing wife, even as the rest of the apostles and the brothers of the Lord and Cephas? Or do only Barnabas and I not have a right to refrain from working?
