'Right' in the Bible

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?

If others share the right over you, do we not more? Nevertheless, we did not use this right, but we endure all things so that we will cause no hindrance to the gospel of Christ.

What then is my reward? That, when I preach the gospel, I may offer the gospel without charge, so as not to make full use of my right in the gospel.
