1 Corinthians 9:7

What soldier ever serves at his own expense? Who plants a vineyard, and does not eat of its fruit? Or who feeds a flock, and does not drink from the flock's milk?

Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock?
