Leviticus 27:29-34

²⁹'No devoted thing, which is devoted of man, is ransomed, it is surely put to death.

³⁰And all tithe of the land, of the seed of the land, of the fruit of the tree, is Jehovah's — holy to Jehovah.

³¹'And if a man really redeem any of his tithe, its fifth he addeth to it.

³²'And all the tithe of the herd and of the flock — all that passeth by under the rod — the tenth is holy to Jehovah;

³³he enquireth not between good and bad, nor doth he change it; and if he really change it — then it hath been — it and its exchange is holy; it is not redeemed.'

³⁴These are the commands which Jehovah hath commanded Moses for the sons of Israel, in mount Sinai.
