33 He may not make search to see if it is good or bad, or make any changes in it; and if he makes exchange of it for another, the two will be holy; he will not get them back again.

Matthew Henry's Commentary on Leviticus 27:33

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.
