Leviticus 27:23-27

²³the priest shall determine the price by the number of years till to the jubilee, and he that avowed the field shall give the price thereof to the Lord;

²⁴forsooth in the jubilee it shall turn again to the former lord that sold it, and he shall have it into the heritage of his possession.

²⁵All the appraising, or value, shall be weighed by the shekel of the saintuary; a shekel hath twenty half-pence.

²⁶No man may hallow and avow the first engendered things that pertain to the Lord, whether it is ox, or sheep, they be the Lord’s part.

²⁷That if the beast is unclean that is avowed, he that offered it shall again-buy it after the value that it is appraised, and he shall add to the fifth part of the price; if he will not again-buy it, it shall be sold to another man, for as much as it is appraised.
