Didache 13:1-6

¹But every true prophet who wants to live among you is worthy of his support.

²So also a true teacher is himself worthy, as the workman, of his support.

³Every first-fruit, therefore, of the products of wine-press and threshing-floor, of oxen and of sheep, you shall take and give to the prophets, for they are your high priests.

⁴But if you have no prophet, give it to the poor.

⁵If you make a batch of dough, take the first-fruit and give according to the commandment.

⁶So also when you open a jar of wine or of oil, take the first-fruit and give it to the prophets; and of money (silver) and clothing and every possession, take the first-fruit, as it may seem good to you, and give according to the commandment.
