הלכה על ויקרא 21:23

That one with a blemish not enter the entire sanctuary: That one with a blemish not enter the sanctuary in its entirety - meaning to say the altar, between the chamber and the altar and all the rest of the places in the sanctuary, as it is stated (Leviticus 21:23), "But to the curtain he shall not come and to the altar he shall not come." And it is elucidated in Sifra, Emor, Chapter 3:10 that these two negative commandments of the curtain and the altar do not suffice, one without the [other]. And each of them comes to complete the law as one matter - and it is to distance the place that is forbidden for them to enter in [from them].
