Parashas Acharei Mos · Passuk 16:08
Chabad.org — English translation + Rashi
Torah Temima points to Toras Kohanim.
English: “To Azazel” — what is Azazel? One teaching: that it be hard and steep; one might think in a settled area — therefore Scripture says “in the wilderness.”
Meaning of Azazel
Azazel is a harsh mountain in the wilderness, not a settled place.
