For the Scripture says, "You shall not muzzle the ox when it treads out the grain." And, "The laborer is worthy of his wages."
double honour: The first honor is the esteem given to those who have met the qualifications and have been appointed to the office. The second honor is money or material support for one who gives himself to the work of caring for the flock and the gospel. Those who teach and preach are here regarded as laborers who are worthy of support. Verse 18 is proof that financial support is here considered, for he quotes from Deuteronomy 25:4 and the words of Jesus in Luke 10:7.
