30 "Every tithe of the land, whether of the seed of the land or of the fruit of the trees, is the Lord's; it is holy to the Lord. 31 If a man wishes to redeem some of his tithe, he shall add a fifth to it. 32 And every tithe of herds and flocks, every tenth animal of all that pass under the herdsman's staff, shall be holy to the Lord. 33 One shall not differentiate between good or bad, neither shall he make a substitute for it; and if he does substitute for it, then both it and the substitute shall be holy; it shall not be redeemed."
Matthew Henry's Commentary on Leviticus 27:30-33
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.
