11 If it concerns any unclean animal that may not be brought as an offering to the Lord, the animal shall be presented before the priest. 12 The priest shall assess it: whether good or bad, according to the assessment of the priest, so it shall be. 13 But if it is to be redeemed, one-fifth must be added to the assessment.
Matthew Henry's Commentary on Leviticus 27:11-13
Commentary on Leviticus 27:1-13
(Read Leviticus 27:1-13)
Zeal for the service of God disposed the Israelites, on some occasions, to dedicate themselves or their children to the service of the Lord, in his house for life. Some persons who thus dedicated themselves might be employed as assistants; in general they were to be redeemed for a value. It is good to be zealously affected and liberally disposed for the Lord's service; but the matter should be well weighed, and prudence should direct as to what we do; else rash vows and hesitation in doing them will dishonour God, and trouble our own minds.
