אַ֣ךְ אֶל־הַפָּרֹ֜כֶת לֹ֣א יָבֹ֗א וְאֶל־הַמִּזְבֵּ֛חַ לֹ֥א יִגַּ֖שׁ כִּֽי־מ֣וּם בּ֑וֹ וְלֹ֤א יְחַלֵּל֙ אֶת־מִקְדָּשַׁ֔י כִּ֛י אֲנִ֥י יְהוָ֖ה מְקַדְּשָֽׁם׃
Only he shall not go in unto the veil, nor come nigh unto the altar, because he hath a blemish; that he profane not My holy places; for I am the LORD who sanctify them.
Sefer HaChinukh
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].
