Acharei Mot, Chapter 1
1) (Vayikra 16:3) "With this shall Aaron come to the holy place: with a young bullock for a sin-offering and a ram for a burnt-offering." "With this": What is the intent of this? Because it is written "to the holy place … before the ark cover which is on the ark," I might think that this applies only to a holy place where there is an ark and an ark cover. Whence do I derive the same for a holy place where there is no ark and ark cover? From "With this shall Aaron come to the holy place" — to equate (for this purpose) a holy place where there is an ark and an ark cover to one where there is not.
