1 Corinthians 9:14

Even so did the Lord ordain (outw kai o Kurio dietaxen). Just as God gave orders about the priests in the temple, so did the Lord Jesus give orders for those who preach the gospel to live out of the gospel (ek tou euaggeliou zhn). Evidently Paul was familiar with the words of Jesus in Matthew 10:10 ; Luke 10:7 either in oral or written form. He has made his argument for the minister's salary complete for all time.
