Leviticus 27:9 Meaning and Commentary

Leviticus 27:9

And if [it be] a beast whereof men bring an offering to the
Lord
That is, it such a creature is devoted, which is of that kind which are used in sacrifice to the Lord, such as bullocks, sheep, goats, rams, and lambs:

all that [any man] giveth of such unto the Lord shall be holy;
shall be set apart to sacred uses, and not applied to profane or common uses, but either were for the use of the altar or of the priests; or the price of them for the repair of the sanctuary, according as they were devoted.

Leviticus 27:9 In-Context

8 If any of you make a vow and are too poor to pay the standard price, you shall bring the person to the priest, and the priest will set a lower price, according to your ability to pay.

9 If your vow concerns an animal that is acceptable as an offering to the Lord, then every gift made to the Lord is sacred,

10 and you may not substitute another animal for it. If you do, both animals belong to the Lord.

11 But if your vow concerns a ritually unclean animal, which is not acceptable as an offering to the Lord, you shall take the animal to the priest.
