1 Corinthians 9:5

Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas? (KJV)

Then: Fee explains there were four methods of supporting traveling philosophers in the Graeco-Roman world: by patronage, by fees, by work, or by begging. If Paul was a legitimate apostle they would be paying him or he would have someone's patronage. The lesser philosophers did other work or begged. Paul's defense here is an unspoken answer to his rhetorical question. They did have the right to be paid for their work. Henry adds that that support also extended to whoever traveled with them, wives, sisiters, fellow apostles and workers.

Now: The issue is settled. Congregations pay for the work of the pastors - unfortunately, sometimes expecting the pastor to do it all. A church like that will never grow.
