New Defender's Study Bible Notes
5:17 double honor. Some of the elders may be responsible as general overseers (or bishops); some may be pastors (or teachers, feeding the flock); some may do both. In any case, those who render this service faithfully and effectively deserve “double honor,” which presumably means (in light of the next verse) double remuneration. They may not need or request it, following Paul’s regular example, but they are deserving of it. It is the responsibility of the congregation (presumably as represented by the deacons) to be sensitive to this situation.
5:18 the scripture saith. This quotation from Deuteronomy 25:4 was also cited in I Corinthians 9:7-11, specifically verse 9.
5:18 worthy of his reward. This reference is a remarkable testimony to the divine inspiration of the gospel of Luke, with Paul quoting Luke 10:7 as authoritative Scripture. Paul had been accompanied by Luke on some of his earlier missionary voyages. Luke would even be with him in his last days (II Timothy 4:11). Paul probably had frequent contact with his physician throughout his later life. He must have had ample opportunity to read Luke’s gospel, perhaps even helping him with its composition. He realized not only that it was truly a product of the Spirit’s inspiration, but also that these particular words had been spoken by the Lord Jesus, and thus were of special importance in this connection.
