Leviticus 27:28-29

28But a  no devoted thing that a man devotes to the  Lord, of anything that he has, whether man or beast, or of his inherited field, shall be sold or redeemed; every devoted thing is most holy to the  Lord. 29 b  No one devoted, who is to be devoted for destruction
That is, set apart ( devoted) as an offering to the Lord (for destruction)
from mankind, shall be ransomed; he shall surely be put to death.
