Key verses: 
1 Corinthians 9:5-7 New King James Version (NKJV)
5 Do we have no right to take along [a]a believing wife, as do also the other apostles, the brothers of the Lord, and Cephas? 6 Or is it only Barnabas and I who have no right to refrain from working? 7 Who ever goes to war at his own expense? Who plants a vineyard and does not eat of its fruit? Or who tends a flock and does not drink of the milk of the flock?
