1 Corinthians 9:4-6 have we no authority to eat and to drink?

MLV⁽ⁱ⁾ ⁴ have we no authority to eat and to drink? ⁵ Have we no authority to lead around a wife, (a sister in the Lord), even as the rest of the apostles and the brethren of the Lord and Cephas? ⁶ Or is it only Barnabas and I who have no authority not to work?
