Leviticus 27:11

And if it be any unclean beast, of which they do not offer an oblation unto Jehovah, then he shall set the beast before the priest;

“If the vow involves any of the unclean animals that may not be brought as an offering to the LORD, the animal must be presented before the priest.

And if it is any unclean animal that may not be offered as an offering to the LORD, then he shall stand the animal before the priest,

And if it be any unclean beast, of which they do not offer a sacrifice unto the LORD, then he shall present the beast before the priest:

If, however, it is any unclean animal of the kind which one does not present as an offering to the LORD, then he shall place the animal before the priest.

If what they vowed is a ceremonially unclean animal—one that is not acceptable as an offering to the LORD—the animal must be presented to the priest,

If it is an unclean animal which they do not offer as a sacrifice to the LORD, then he shall present the animal before the priest;

If your vow involves an unclean animal—one that is not acceptable as an offering to the LORD—then you must bring the animal to the priest.
