כָּל כֹּהֵן הַכָּשֵׁר לַעֲבוֹדָה אִם שָׁתָה יַיִן אָסוּר לוֹ לְהִכָּנֵס מִן הַמִּזְבֵּחַ וּלְפָנִים. וְאִם נִכְנַס וְעָבַד עֲבוֹדָתוֹ פְּסוּלָה וְחַיָּב מִיתָה בִּידֵי שָׁמַיִם שֶׁנֶּאֱמַר (ויקרא י ט) "וְלֹא תָמֻתוּ". וְהוּא שֶׁשָּׁתָה רְבִיעִית יַיִן חַי בְּבַת אַחַת מִיַּיִן שֶׁעָבְרוּ עָלָיו אַרְבָּעִים יוֹם. אֲבָל אִם שָׁתָה פָּחוֹת מֵרְבִיעִית יַיִן. אוֹ שָׁתָה רְבִיעִית וְהִפְסִיק בָּהּ. אוֹ מְזָגָהּ בְּמַיִם. אוֹ שֶׁשָּׁתָה יַיִן מִגִּתּוֹ בְּתוֹךְ אַרְבָּעִים אֲפִלּוּ יֶתֶר מֵרְבִיעִית. פָּטוּר וְאֵינוֹ מְחַלֵּל עֲבוֹדָה. שָׁתָה יֶתֶר מֵרְבִיעִית מִן הַיַּיִן אַף עַל פִּי שֶׁהָיָה מָזוּג וְאַף עַל פִּי שֶׁהִפְסִיק וְשָׁהָה מְעַט מְעַט חַיָּב מִיתָה וּפוֹסֵל הָעֲבוֹדָה:
Whenever a priest who is fit to perform Temple service drinks wine, he is forbidden to enter the area of the Altar or [proceed] beyond there. If he entered [that area] and performed service, his service is invalid and he is liable for death at the hand of heaven, as [Leviticus 10:9] states: "[Do not drink intoxicating wine...] so that you do not die." The above applies provided one drinks a revi'it of undiluted wine at one time, provided the wine is over 40 days old. If, however, one drank less than a revi'it of wine, one drank a revi'it intermittently, one mixed it with water, or one drank even more than a revi'it of wine from the vat, i.e., within 40 days of its being brought into being, he is exempt and his service is not profaned. If he drank more than a revi'it of wine, even though it was diluted and even though he drank it intermittently, he is liable for death and his service is invalidated.
