Ver. 10. Then it and the exchange thereof.] For a punishment of his instability and lightness.

Lev 27:10. He shall not alter it, nor change it — Two words expressing the same thing more emphatically; that is, he shall in no wise change it, neither for one of the same nor of another kind: partly because God would preserve the sanctity and reverence of consecrated things, and therefore would not have them alienated; and partly to prevent abuses of them by those who on this pretence might exchange what had been vowed for the worse. It and the exchange — That is, both the thing first vowed, and the thing offered and given in exchange. This was inflicted upon him as a just penalty for his levity in such weighty matters.

Verse 10. He shall not alter it, nor change it, a good for a bad, c.] Whatever was consecrated to God by a vow, or purpose of heart, was considered from that moment as the Lord's property to change which was impiety; to withhold it, sacrilege. Reader, hast thou ever dedicated thyself, or any part of thy property, to the service of thy Maker? If so, hast thou paid thy vows? Or hast thou altered thy purpose, or changed thy offering? Has he received from thy hands a bad for a good? Wast thou not vowed and consecrated to God in thy baptism? Are his vows still upon thee? Hast thou "renounced the devil and all his works, the pomps and vanities of this wicked world, and all the sinful lusts of the flesh?" Dost thou feel thyself bound "to keep God's holy will and commandments, and walk in the same all the days of thy life?" Was not this thy baptismal covenant? And hast thou renounced IT? Take heed! God is not mocked: that which thou sowest, thou shalt also reap. If thou rob God of thy heart, he will deprive thee of his heaven.

(10) He shall not alter it, nor change it.—The identical animal vowed is to be delivered; no change whatever, even if it is in the substitution of a better for an inferior animal, is permitted. The stress laid upon this part of the enactment is indicated by the employment here of two verbs of the same import. If he who vows does change the one he dedicated to the Lord, both the animals, the one he originally vowed and the one he substituted for it, are alike holy, and must be delivered to the sanctuary.

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).

A good for a bad, or a bad for a good; partly because God would preserve the sanctity and reverence of consecrated things, and therefore would not have them alienated; and partly to prevent abuses of them who on this pretence might exchange it for the worse, as reserving the judgment to himself.

The exchange thereof, i.e. both the thing first vowed, and thing offered or given in exchange. This was inflicted upon him as a just penalty for his rashness and levity in such weighty matters.

10. He shall not alter — He shall not modify the terms of his vow by substituting any thing else than the animal vowed.

Nor change — Another animal of the same species will not be accepted. “Whatever was consecrated to God by a vow or purpose of heart was considered from that moment as the Lord’s property; to change which was impiety; to withdraw, sacrilege.” — Bush. God will permit no dictation respecting the disposal of his own.

It and the exchange — As a penalty for his attempted usurpation of a divine prerogative, both animals shall be holy, and tradition adds that the intermeddler was scourged besides. The tendency of this law was to discourage rash vows, and to impress both Jews and Christians with the inviolable sacredness of the object consecrated, no part of which can ever be safely recalled.

טוב ברע [HE SHALL NEITHER CHANGE IT NOR EXCHANGE IT] A GOOD FOR A BAD — i. e. he shall not give in exchange a perfect animal of a non-sacred character for one devoted to the Sanctuary but having some blemish (cf. Rashi on Temurah 9a on ‎‎‎מתני' טוב ברע),

‎‎‎או רע בטוב‎ OR A BAD FOR A GOOD — It follows à fortiori that he must not give in exchange a perfect animal for another perfect one, or one with a blemish for another with a blemish (Temurah 9a).
