Parashas Vayikra · Aliyah 2 · Passuk 16
Chabad.org — English translation + Rashi
Torah Temima points to Meilah 12a (verified; place of the ashes includes inner-altar and menorah ashes).
English: “To the place of the ashes” — teaches that it is a mitzvah to clear the altar of ashes… apply it to the inner altar… From where the menorah? The Torah states “the ashes.”
Custom (extra force of the definite article / placement language).
Ashes from the inner altar and the menorah are also deposited at the eastern place of ashes by the outer altar.
