Bible Phrasing: 1 Timothy 5:17-21
The Command: "Let the elders who rule well be considered worthy of double honor"
The Caveat: "Especially those who labor in preaching and teaching"
Two main questions of clarification are worth asking: 1) How does "especially" relate to the command? and 2) How do the Scriptures Paul cites support the consideration for double honor for ruling elders?
How does "especially" relate to the command?
Does "especially" modify the first or second part of the command? If the adverb modifies the first part of the command, Paul strongly insinuates that "those who labor in preaching and teaching" are to be differentiated from the broad category of "elders who rule well." If the adverb modifies the second part of the command, "be considered worthy of double honor," then Paul strongly suggests somehow that "those who labor in preaching and teaching" are worthy of a greater double honor.
The likely interpretation is that Paul envisions two groups of elders: those who rule well in general, and those who rule well by preaching and teaching. Although all elders should be able to teach (1 Timothy 3:2), not all elders will labor primarily in those specific ways. The text does not suggest that teaching and preaching gives access to "more" double honor ("especially those who preach and teach are worthy of double honor"). "Double honor" is reserved for both categories of elders who rule well. The keyword is "well."
How do the Scriptures support the consideration for double honor for ruling elders?
The consideration for double honor is grounded in two passages of Scripture. The first passage is from Deuteronomy 25:4, "you shall not muzzle an ox when it treads out the grain." The second passage is: "the laborer deserves his wages," most likely a reference to Jesus's words from Luke 10:7.
Why does Paul ground the support of elders on these two passages? The Luke 10:7 passage is more obvious in this context: it is right and good for pastors who serve faithfully to receive hospitality and generosity from the church.
The Deuteronomy 25:4 passage is less clear. What do oxen have to do with elders? Both labor and both have rights to be remunerated for their labor. God provides food for the oxen as they labor, which is why Israel was commanded not to muzzle them. Similarly, elders are entitled to their wages as they labor, which is why Paul commands the church to be generous to their elders.
PART 2
In the second part, 5:19-20, Paul stipulates two main ideas. First, charges against elders should be well-established. And second, Paul instructs that those who are in persistent sin should be rebuked publicly.
The first stipulation contains a negative command (do not), an exception (except on...), and a qualifier (two or three witnesses). The second stipulation contains a qualifier (as for those...), a positive command (rebuke them...), and a reason for the command (so that...).
These two commands are necessary for the church and fit Paul's major thesis in 1 Timothy 3:14–15. Elders, perhaps more than any other church member, are open to accusations because of their public ministry. It is important, therefore, to allow admission of charges and public rebukes to elders who abuse their position in the household of God. But these verses stipulate features to protect elders against baseless accusations. It is unlikely that two or three witnesses would admit a charge if it were baseless. Deuteronomy 19:15, from where the caveat of two or three witnesses derives, is adamant that disputes are in "the presence of the Lord." This is why Paul concludes this section with verse 21.
PART 3
Paul's charge to Timothy in verse 21 functions as a natural conclusion to the previous sections. First, "these instructions" likely refers back to the material contained in 5:8–20. The first occurrence of "these things" is in 3:14, which includes the material from chapters 1-3. Paul uses "these things" more frequently in the latter half of the letter (4:6, 11; 5:7, 21; 6:2, 11) to summarize sections of commands. So "these instructions" in 5:21 likely summarizes commands related to widows and elders.
As mentioned above, 5:21 captures the theme of Deuteronomy 19:15, which explains that disputes are to be held in "the presence of the Lord," the covenant God. Paul continues that thought here, "in the presence of God," but adds "Christ Jesus," and "elect angels." In other words, a large swath of heavenly beings, but most importantly, God himself, are present and can observe Timothy's keeping of these rules. Several observations are noteworthy.
1) "These instructions" are from God himself, which is why Paul binds Timothy to keep them. The instructions are authoritative, not because Paul thinks they may be good for building community; rather, they are commands instituted by God and should be held in high regard.
2) Secondly, invoking the presence of God, Christ Jesus, and the elect angels, requires Timothy to look past the Apostle Paul to the authority undergirding the apostle's ministry. Paul is and always has been a mere messenger of God's own pleasure. Paul is binding Timothy to the authority that surpasses even his apostolic authority; the very authority of God.
3) Timothy is to keep these instructions "without prejudging." Paul clarifies what he means by prejudging: Timothy is to do nothing "from partiality." It is especially important for Timothy to remain above board in the way he handles sensitive issues like qualifying and providing for widows or receiving charges and accusations against elders. If Timothy is tempted to offer preferential treatment, it could negatively impact God's household, resulting in a failed ministry. Paul wants to impress on Timothy the weight of the task before him. It's a task that requires faithfulness, judiciousness, and impartiality.
