1st Corinthians 9:6

3 My defence to those who examine me in this;

4 have we not authority to eat and to drink?

5 have we not authority a sister -- a wife -- to lead about, as also the other apostles, and the brethren of the Lord, and Cephas?

6 or only I and Barnabas, have we not authority -- not to work?

7 who doth serve as a soldier at his own charges at any time? who doth plant a vineyard, and of its fruit doth not eat? or who doth feed a flock, and of the milk of the flock doth not eat?

8 According to man do I speak these things? or doth not also the law say these things?

9 for in the law of Moses it hath been written, `thou shalt not muzzle an ox treading out corn;` for the oxen doth God care?
