Bechoros 7:6-7

Bechoros 7:6

Additional blemishes that disqualify a kohein from serving: his ankles or knees bang together; his knees don’t touch when his feet are together; he has a lump protruding from his thumb; his heel sticks out the back; the sole of his foot is wide like a goose’s. If his fingers lie one on top of the next or are webbed until the joint, he can serve; similarly, if they’re webbed past the joint and he cuts it, he can serve. If he had an extra digit and he cut it off, then if that digit had a bone he may not serve; if it didn’t, then he may. If he has an extra digit on each hand and foot, six on each for a total of 24, Rabbi Yehuda says he may serve but the Sages say that he may not. Rebbi says that an ambidextrous person may not serve but the Sages say that he may. Being dark-skinned, red-skinned, albino, extremely tall and thin, a little person, having congenital deafness, lacking mental competence, being intoxicated, and having clean signs of tzaraas disqualify a person from serving but do not disqualify animals for use as sacrifices. Rabban Shimon ben Gamliel says an animal with a developmental disability is not considered choice (so it may not be offered as a sacrifice). Rabbi Eliezer adds dangling warts to the list of blemishes that disqualify a human being but not an animal.

Bechoros 7:7

The following things do not disqualify humans but they do disqualify animals: a father and his son (i.e., father-and-son kohanim may serve on the same day but father-and-son animals may not be offered on the same day), a treifa, being born via C-section, being used to commit a sexual offense or having killed a person. A kohein who married a prohibited woman may not serve until he vows not to derive any benefit from her (which will ultimately result in him divorcing her). A kohein who renders himself ritually unclean through contact with the dead may not serve until he commits not to do so any longer.
