Parashas Acharei Mos · Passuk 16:19
Chabad.org — English translation + Rashi
Torah Temima points to Toras Kohanim.
English: “And he shall purify it” — from the impurity; “and sanctify it” — to sanctify it for its purpose.
Purify and sanctify
Two effects: removal of tumah and restoration of the altar’s sanctity for service.
