27:10 He shall not alter it, nor change it, a good for a bad, or a bad for a good: and if he shall at all change beast for beast, then it and the exchange thereof shall be {g} holy.
(g) That is, consecrate to the Lord.
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 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. It and the exchange - That is, both the thing first vowed, and the thing offered or given in exchange. This was inflicted upon him as a just penalty for his levity in such weighty matters.
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.
