Parashas Acharei Mos · Passuk 17:03
Chabad.org — English translation + Rashi
Torah Temima points to Zevachim 108b.
English: “Any man” — the Torah spoke in the language of ordinary people (no special derashah from the doubled word).
Dibrah Torah kilshon bnei adam
The doubled “ish ish” is ordinary biblical style, not an independent inclusion.
