קְדֹשִׁ֤ים יִהְיוּ֙ לֵאלֹ֣הֵיהֶ֔ם וְלֹ֣א יְחַלְּל֔וּ שֵׁ֖ם אֱלֹהֵיהֶ֑ם כִּי֩ אֶת־אִשֵּׁ֨י יְהוָ֜ה לֶ֧חֶם אֱלֹהֵיהֶ֛ם הֵ֥ם מַקְרִיבִ֖ם וְהָ֥יוּ קֹֽדֶשׁ׃
Sila ay magiging banal sa kanilang Diyos, at hindi nila lalapastanganin ang pangalan ng kanilang Diyos; sapagkat ang mga handog na pinaraan sa apoy para sa Walang-Hanggan, ang tinapay ng kanilang Diyos, ang siyang inihahandog nila; at sila ay magiging banal.
Shenei Luchot HaBerit
Commandment 265 forbids a priest who has purified himself -but still awaits sunset after ritual immersion- to perform sacrificial service. At that point he is still in the state of a secondary degree of ritual impurity. Concerning this the Torah writes: ולא יחללו שם אלוקיהם (21,6). Sanhedrin 83 explains that as the verse is not needed, because the information contained in it is already known, it is available to derive additional laws of a related matter, in this case the continued טומאה status of someone awaiting the sun to set after he has completed the ritual of purification. The similarity of the expressions חילול on both occasions lends weight to the validity of this rule.
