And if it be a {f} beast, whereof men bring an offering unto the LORD, all that any man giveth of such unto the LORD shall be holy.

(f) Which is clean, Le 11:2.

Wesley's Notes

27:9 Whereof men bring an offering - That is, a clean beast. Giveth - Voweth to give: Shall be holy - Consecrated to God, either to be sacrificed, or to be given to the priest, according to the manner of the vow, and the intention of him that voweth.

Jamieson-Fausset-Brown Bible Commentary

9-13. if it be a beast, whereof men bring an offering unto the Lord-a clean beast. After it had been vowed, it could neither be employed in common purposes nor exchanged for an equivalent-it must be sacrificed-or if, through some discovered blemish, it was unsuitable for the altar, it might be sold, and the money applied for the sacred service. If an unclean beast-such as an ass or camel, for instance, had been vowed, it was to be appropriated to the use of the priest at the estimated value, or it might be redeemed by the person vowing on payment of that value, and the additional fine of a fifth more.

Matthew Henry's Concise Commentary

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.
