'Laborer' in the Bible

no wallet for your journey, neither two coats, nor shoes, nor staff: for the laborer is worthy of his food.

Stay in that house, eating and drinking what they give you; for the laborer is worthy of his wages. Do not keep moving from house to house.

Now to a laborer, his wages are not credited as a favor or a gift, but as an obligation [something owed to him].

For the Scripture says:Do not muzzle an oxwhile it is treading out the grain, and,the worker is worthy of his wages.
