LEV872 LEV8 It is a positive commandment to accord honor to a kohen: [a direct mail descendent of Aaron] since Scripture says, You shall hallow him [this verse] – – which means to make him holy and prepare him, that he should be fit and ready to offer up sacrifices [at the Sanctuary], and also to treat him with honor, making him first in every matter of holiness: to begin as the first at the reading of the Torah, to be the first to say the benediction at a meal, and to take a fine portion at the start. We are duty-bound to hallow him [thus] even against his will if he does not wish it, since Scripture states, You shall hallow him--even against his will. Even if a kohen has a disfiguring defect, and thus is not fit for Temple service, we are obligated to honor him.
