Midrash su Levitico 4:21

3) "And he shall take the entire bullock outside the camp": Outside the three camps, or outside one camp? When it is written in respect to the congregation (Vayikra 1:21): "And he shall take the bullock outside the camp" — let this ("outside the camp") not be stated, for it is already written (Vayikra 1:21): "and he shall burn it as he burned the first bullock." Why, then, is "outside the camp" stated? To add a second camp.

8) (Vayikra 4:21): "And he shall take the bullock outside the camp": outside the three camps (see Chapter 5:4); "and he shall burn it as he burned the first bullock": So that if the bullock of the high-priest and the bullock of the congregation are waiting (sacrifice), the first takes precedence in all services (see Section 4:1).

9) I might think that even the idolatry goats precede it (the bullock of the congregation). And it would, indeed, follow (that they should), viz.: If the bullock of an individual (the high-priest) precedes it, should not the idolatry goats of the congregation precede it! It is, therefore, written (to negate this): ("the first) bullock." The bullock is first, and not the idolatry goats.
