(11) And if it be any unclean beast.--That is, if what he vows consists of an unclean beast, which does not belong to the three kinds of sacrificial quadrupeds, and which cannot therefore be sacrificed on the altar. According to the authorities during the second Temple, however, the expression "unclean beast" here denotes defective sacrificial animals, such as oxen, sheep, and goats with blemishes, which have become unlawful for the altar.
Verses 11-13. - An unclean animal, which might not be sacrificed, if vowed, was to be valued at a price fixed by the priest. If its original owner took it back again, he was to pay this price and one-fifth more than the sum named; if he did not, it became the property of the sanctuary. The words, the priest shall value it, whether it be good or bad, should rather be rendered, the priest shall estimate it between good and bad, that is, at a moderate price, as though it were neither very good nor very bad. And so in the next verse.
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.
And if it be any unclean beast, of which they do not offer a sacrifice unto the Lord,.... Any creature, excepting a dog, the price of which was not to be brought into the house of the Lord; besides oxen, sheep, goats, rams, and lambs; though some understand it even of such that have blemishes on them, and so not fit to be offered unto the Lord; so Jarchi and others (x):
then he shall present the beast before the priest; to be viewed, examined, and judged of as to its worth, and a value put upon it, that it might be sold or redeemed, as no other but a beast might; so it is observed birds, wood, frankincense, and ministering vessels, have no redemption, for it is only said a beast (y).
