'Right' in the Bible

But see lest anywise this your right to eat itself be a stumbling-block to the weak.

Have we not a right to eat and to drink?

have we not a right to take round a sister as wife, as also the other apostles, and the brethren of the Lord, and Cephas?

Or I alone and Barnabas, have we not a right not to work?

If others partake of this right over you, should not rather we? But we have not used this right, but we bear all things, that we may put no hindrance in the way of the glad tidings of the Christ.

What is the reward then that I have? That in announcing the glad tidings I make the glad tidings costless to others, so as not to have made use, as belonging to me, of my right in announcing the glad tidings.
