1 Timothy 5:8, 17-18

But if any provideth not for his own, and specially his own household, he hath denied the faith, and is worse than an unbeliever.

Let the elders that rule well be counted worthy of double honor, especially those who labor in the word and in teaching. For the scripture saith, Thou shalt not muzzle the ox when he treadeth out the corn. And, The laborer is worthy of his hire.
