1 Timothy 5:18

18 for the scripture says, "You shall not muzzle an ox while it is treading out the grain," and, "The laborer deserves to be paid."

1 Timothy 5:18 In-Context

16 If any believing woman has relatives who are really widows, let her assist them; let the church not be burdened, so that it can assist those who are real widows.
17 Let the elders who rule well be considered worthy of double honor, especially those who labor in preaching and teaching;
18 for the scripture says, "You shall not muzzle an ox while it is treading out the grain," and, "The laborer deserves to be paid."
19 Never accept any accusation against an elder except on the evidence of two or three witnesses.
20 As for those who persist in sin, rebuke them in the presence of all, so that the rest also may stand in fear.
