1 Corinthians 9:4-6 Do we not have authority to eat and to drink?

MKJV⁽ⁱ⁾ ⁴ Do we not have authority to eat and to drink? ⁵ Do we not have authority to lead about a sister, a wife, as well as other apostles, and as the brothers of the Lord do, and Cephas? ⁶ Or is it only Barnabas and I who have no authority whether not to work?
