Leviticus 27:29-34

²⁹None devoted, which shall be devoted of men, shall be redeemed; but shall surely be put to death.

³⁰And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, is the Lord’s: it is holy unto the Lord.

³¹And if a man will at all redeem ought of his tithes, he shall add thereto the fifth part thereof.

³²And 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.

³³He shall not search whether it be good or bad, neither shall he change it: and if he change it at all, then both it and the change thereof shall be holy; it shall not be redeemed.

³⁴These are the commandments, which the Lord commanded Moses for the children of Israel in mount Sinai.
