1 Timothy 5:17
17Let the elders who rule well be counted worthy of double honor, especially those who labor in the word and in teaching.
Elders who rule well are worthy of double honor, especially those who labor in the word and in teaching. Wesley: faithful stewards, a more abundant provision, because they will employ it to God's glory; especially those who labor diligently in the word.
In practice: honor is both respect and support. Elders can rule well or poorly; the "well" is a condition. Grace that calls a man to teach also calls the church not to starve the labor by which they heard the gospel.
Calvin: elder here is office, not merely age. Double honor is compared with the honor already due to widows; elders who rule well, especially those who labor in word and doctrine, should receive even more. Honor is due to the work, not to a bare title.
God gives pastors and ruling elders as gifts. The Spirit who called them to labor also commands the flock to support them. Ingratitude that pinches the teacher is one of Satan's old tricks against the Word.
