Didache 13

But every true prophet who will set- tle among you is worthy of his support. Likewise a true teacher, he also is worthy, like the workman, of his support. Every firstfruit, then, of the products of wine-press and threshing-floor, or oxen and of sheep, thou shalt take and give to the prophets; for they are your high-priests. but if ye have no prophet, give it to the poor. If thou makest a baking of bread, take the first of it and give according to the commandment. In like manner when thou openest a jar of wine or oil, take the first of it and give to the prophets; and of money and clothing and every possession take the first, as seems right to thee, and give according to the commandment.
