Therefore thou shalt take the firstfruit[*](Their payment by firstfruits) 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.

If thou makest bread, take the first-fruits, and give it according to the commandment.

Likewise when thou openest a jar of wine or oil, give the firstfruits to the prophets.
