'Right' in the Bible

Have we no right to eat and to drink?

Have we no right to take along a wife who is a believer, even as the rest of the apostles, and the brothers of the Lord, and Cephas?

Or have only Barnabas and I no right to not work?

If others partake of this right over you, don't we yet more? Nevertheless we did not use this right, but we bear all things, that we may cause no hindrance to the Good News of Christ.
