1 Corinthians 9:6-7 Or is it only Barnabas and I who have no authority whether not to work?

MKJV⁽ⁱ⁾ ⁶ Or is it only Barnabas and I who have no authority whether not to work? ⁷ Who serves as a soldier at his own wages at any time? Who plants a vineyard and does not eat of its fruit? Or who feeds a flock and does not partake of the milk of the flock?
