"And all the tithe of the land, or of the fruit of the tree, is the Lord's: it is holy unto the Lord. And if a man will at all redeem ought of his tithes, he shall add thereto the fifth part thereof And concerning the tithe of the herd, or of the flock, even of whatsoever passeth under the rod, the tenth shall be holy unto the LORD. He shall not search whether it be good or bad, neither shall he change it: and the change thereof shall be holy; it shall not be redeemed. These are the commandments, which the Lord commanded Moses for the children of Israel in mount Sinai."
Leviticus 27:30-34
