כָּל כֹּהֵן שֶׁיֵּשׁ בּוֹ מוּם בֵּין מוּם קָבוּעַ בֵּין מוּם עוֹבֵר לֹא יִכָּנֵס לַמִּקְדָּשׁ מִן הַמִּזְבֵּחַ וּלְפָנִים שֶׁנֶּאֱמַר (ויקרא כא כג) "אֶל הַפָּרֹכֶת לֹא יָבֹא וְאֶל הַמִּזְבֵּחַ לֹא יִגַּשׁ". וְאִם עָבַר וְנִכְנַס לוֹקֶה אַף עַל פִּי שֶׁלֹּא עָבַד. וְאִם עָבַד בַּמִּקְדָּשׁ פָּסַל וְחִלֵּל עֲבוֹדָה וְלוֹקֶה אַף עַל הָעֲבוֹדָה. שֶׁנֶּאֱמַר (ויקרא כא יז) "אֲשֶׁר יִהְיֶה בוֹ מוּם לֹא יִקְרַב". מִפִּי הַשְּׁמוּעָה לָמְדוּ שֶׁאַזְהָרָה זוֹ שֶׁלֹּא יִקְרַב לַעֲבוֹדָה:
Any priest who has a physical blemish - whether a permanent blemish or a temporary blemish - should not enter the area of the altar and beyond in the Temple, as [Leviticus 21:21-23] states: "[Any man from among the descendants of Aaron the priest who has a blemish...] shall not come near the curtain, nor may he approach the altar. If he transgresses and enters [this area], he is liable for lashes even if he did not perform any service. If he performs service in the Temple, he invalidates and desecrates his service. He is worthy of lashes for the service as well, as [ibid.:17] states: "One who has a blemish shall not draw near [to offer...]." According to the Oral Tradition, we learned that this warning means that he shall not draw near to the Temple service.
