28 'Nevertheless no devoted offering that a man may devote to the Lord of all that he has, both man and beast, or the field of his possession, shall be sold or redeemed; every devoted offering is most holy to the Lord. 29 No person under the ban, who may become doomed to destruction among men, shall be redeemed, but shall surely be put to death. 30 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 to the Lord. 31 If a man wants at all to redeem any of his tithes, he shall add one-fifth to it. 32 And concerning the tithe of the herd or the flock, of whatever passes under the rod, the tenth one shall be holy to the Lord.

Matthew Henry's Commentary on Leviticus 27:28-32

Commentary on Leviticus 27:26-33

(Read Leviticus 27:26-33)

Things or persons devoted, are distinguished from things or persons that were only sanctified. Devoted things were most holy to the Lord, and could neither be taken back nor applied to other purposes. Whatever productions they had the benefit, God must be honoured with the tenth of, if it could be applied. Thus they acknowledge God to be the Owner of their land, the Giver of its fruits, and themselves to be his tenants, and dependants upon him. Thus they gave him thanks for the plenty they enjoyed, and besought his favour in the continuance of it. We are taught to honour the Lord with our substance.
