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:
Context
10 He shall not alter it, nor exchange it, a good for a bad, or a bad for a good. If he shall at all exchange animal for animal, then both it and that for which it is exchanged shall be holy.
11 If it is any unclean animal, of which they do not offer as an offering to the LORD, then he shall set the animal before the priest;
12 and the priest shall evaluate it, whether it is good or bad. As the priest evaluates it, so it shall be.
