וְהַֽמְשַׁלֵּ֤חַ אֶת־הַשָּׂעִיר֙ לַֽעֲזָאזֵ֔ל יְכַבֵּ֣ס בְּגָדָ֔יו וְרָחַ֥ץ אֶת־בְּשָׂר֖וֹ בַּמָּ֑יִם וְאַחֲרֵי־כֵ֖ן יָב֥וֹא אֶל־הַֽמַּחֲנֶֽה׃
And he that letteth go the goat for Azazel shall wash his clothes, and bathe his flesh in water, and afterward he may come into the camp.
Targum Jonathan on Leviticus
And he who led away the goat to Azazel shall wash his clothes, and bathe his flesh in forty seahs of water, and afterward he may enter the camp.
