New Testament

Luke 10:7

4 Do not carry a money bag, a traveler’s bag, or sandals, and greet no one on the road. 5 Whenever you enter a house, first say, ‘May peace be on this house!’ 6 And if a peace-loving person is there, your peace will remain on him, but if not, it will return to you. 7 Stay in that same house, eating and drinking what they give you, for the worker deserves his pay. Do not move around from house to house. 8 Whenever you enter a town and the people welcome you, eat what is set before you. 9 Heal the sick in that town and say to them, ‘The kingdom of God has come upon you!’ 10 But whenever you enter a town and the people do not welcome you, go into its streets and say, 11 ‘Even the dust of your town that clings to our feet we wipe off against you. Nevertheless know this: The kingdom of God has come.’ 12 I tell you, it will be more bearable on that day for Sodom than for that town!

Didache 13:2

1 But every true prophet who wishes to settle among you is worthy of his food. 2 Likewise a true teacher is himself worthy, like the workman, of his food. 3 Therefore thou shalt take the firstfruit of the produce of the winepress and of the threshingfloor and of oxen and sheep, and shalt give them as the firstfruits to the prophets, for they are your high priests. 4 But if you have not a prophet, give to the poor. 5 If thou makest bread, take the firstfruits, and give it according to the commandment. 6 Likewise when thou openest a jar of wine or oil, give the firstfruits to the prophets. 7 Of money also and clothes, and of all your possessions, take the firstfruits, as it seem best to you, and give according to the commandment.
