1 Timothy 5:8, 17-18

But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel.

Let the elders that rule well be counted worthy of double honour, especially they who labour in the word and doctrine. For the scripture saith, Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward.
