An impure person must not eat from sacrifices

'But the person who eats the flesh of the sacrifice of peace offerings which belong to the LORD, in his uncleanness, that person shall be cut off from his people.

Hebrew

כ וְהַנֶּפֶשׁ אֲשֶׁר-תֹּאכַל בָּשָׂר, מִזֶּבַח הַשְּׁלָמִים אֲשֶׁר לַיהוָה, וְטֻמְאָתוֹ, עָלָיו--וְנִכְרְתָה הַנֶּפֶשׁ הַהִוא, מֵעַמֶּיהָ.
