1 Timothy 5:17-18

17The elders who perform their leadership duties well are to be considered worthy of double honor (financial support), especially those who work hard at preaching and teaching [the word of God concerning eternal salvation through Christ].

18For the Scripture says, “You shall not muzzle the ox while it is treading out the grain [to keep it from eating],” and, “The worker is worthy of his wages [he deserves fair compensation].”
