וְהַשֹּׂרֵ֣ף אֹתָ֔ם יְכַבֵּ֣ס בְּגָדָ֔יו וְרָחַ֥ץ אֶת־בְּשָׂר֖וֹ בַּמָּ֑יִם וְאַחֲרֵי־כֵ֖ן יָב֥וֹא אֶל־הַֽמַּחֲנֶֽה׃
And he that burneth them 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 burneth them shall wash his clothes, and bathe his flesh in forty seahs of water, and afterwards he may enter the camp.
