Parashas Acharei Mos · Passuk 16:33
Chabad.org — English translation + Rashi
Torah Temima points to Menachos 27b.
English: One might think that in the Second Temple, lacking ark and kaporet, the sprinklings are not performed; the verse teaches that the place itself that is sanctified for holiness receives the service.
Service in the Second Temple
The Yom Kippur sprinklings are performed even without the ark, directed to the designated holy place.
