“But every true prophet who wishes to settle among you is “worthy of his food.” Likewise a true teacher is himself worthy, like the workman, of his food. Therefore thou shalt take the firstfruit of the produce of the winepress and of the threshing floor and of oxen and sheep, and shalt give them as the firstfruits to the prophets, for they are your high priests. But if you have not a prophet, give to the poor.” – Didache XIII
