Leviticus 27:28

28 Any thing that is devoted to the Lord, whether it be man, or beast, or field, shall not be sold: neither may it be redeemed. Whatsoever is once consecrated shall be holy of holies to the Lord.

27 And if it be an unclean beast, he that offereth it shall redeem it, according to thy estimation, and shall add the fifth part of the price. If he will not redeem it, it shall be sold to another for how much soever it was estimated by thee.
28 Any thing that is devoted to the Lord, whether it be man, or beast, or field, shall not be sold: neither may it be redeemed. Whatsoever is once consecrated shall be holy of holies to the Lord.
