“And the priest shall value it, whether it be good or bad: as thou valuest it, who art the priest, so shall it be.”
King James Version (KJV)
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.
27:11 Unclean - Either for the kind, or for the quality of it; if it were such an one as might not be offered.
27:14 Sanctify his house - By a vow, for of that way and manner of sanctification he speaks in this whole chapter.
