בְּבֹאָ֣ם הַכֹּהֲנִ֗ים וְלֹֽא־יֵצְא֤וּ מֵהַקֹּ֙דֶשׁ֙ אֶל־הֶחָצֵ֣ר הַחִיצוֹנָ֔ה וְשָׁ֞ם יַנִּ֧יחוּ בִגְדֵיהֶ֛ם אֲשֶׁר־יְשָׁרְת֥וּ בָהֶ֖ן כִּֽי־קֹ֣דֶשׁ הֵ֑נָּה ילבשו [וְלָבְשׁוּ֙] בְּגָדִ֣ים אֲחֵרִ֔ים וְקָרְב֖וּ אֶל־אֲשֶׁ֥ר לָעָֽם׃
祭司進去以後，不可從聖所出到外院；他們要把供職時所穿的衣服放在那裡，因為這些衣服是聖的。他們要穿上別的衣服，才可以接近屬於百姓的。
Rashi
but shall there leave their garments, etc., and they will approach those of the people And they may approach to touch the peoples’ garments if they wish, but they must not touch the [garments of] people with the priestly raiment, for they have higher degrees of ritual purity, and ordinary garments have midras contamination on them.
