Leviticus 27:27-29

Revised Standard Version Catholic Edition

²⁷ And if it is an unclean animal, then he shall buy it back at your valuation, and add a fifth to it; or, if it is not redeemed, it shall be sold at your valuation.

²⁸ “But no devoted thing that a man devotes to the Lord, of anything that he has, whether of a man or beast, or of his inherited field, shall be sold or redeemed; every devoted thing is most holy to the Lord. ²⁹ No one devoted, who is to be utterly destroyed from among men, shall be ransomed; he shall be put to death.
