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. 33 He shall not inquire whether it is good or bad, nor shall he exchange it; and if he exchanges it at all, then both it and the one exchanged for it 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.
