Leviticus Chapter 27

27:28-30
Notwithstanding no devoted thing, that a man shall devote unto the Lord of all that he hath, both of man and beast, and of the field of his possession, shall be sold or redeemed: every devoted thing is most holy unto the Lord.
None devoted, which shall be devoted of men, shall be redeemed; but shall surely be put to death.
And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, is the Lord’s: it is holy unto the Lord.
