'Right' in the Bible

But watch out lest somehow this right of yours becomes a cause for stumbling to the weak.

Do we not have the right to eat and drink?

Do we not have the right to take along a sister [as] wife, like the rest of the apostles and the brothers of the Lord and Cephas?

Or do only I and Barnabas not have the right {to refrain from working}?

If others share this right over you, do we not [do so] even more? Yet we have not made use of this right, but we endure all [things], in order that we may not cause any hindrance to the gospel of Christ.

What then is my reward? That [when I] proclaim the gospel, I may offer the gospel free of charge, in order not to make full use of my right in the gospel.
