Leviticus 27:30-34

³⁰All the tithes of the earth, whether of fruits of corn, whether of apples of trees, be the Lord’s part, and be hallowed to him;

³¹soothly if any man will again-buy his tithes, he shall add to the fifth part of those or them;

³²of all the tithes of sheep, and of oxen, and of goats, that pass under the shepherd’s rod, whatever thing cometh to the tenth part, it shall be hallowed to the Lord;

³³it shall not be chosen, neither good, neither evil; neither it shall be changed for another; if any man changeth it, both that, that is changed, and that, for which it is changed, shall be hallowed to the Lord, and it shall not be again-bought.

³⁴These be the commandments which the Lord commanded to Moses, and to the sons of Israel, in the hill or mount of Sinai.
