וְאִ֕ישׁ אֲשֶׁ֥ר יִגַּ֖ע בְּמִשְׁכָּב֑וֹ יְכַבֵּ֧ס בְּגָדָ֛יו וְרָחַ֥ץ בַּמַּ֖יִם וְטָמֵ֥א עַד־הָעָֽרֶב׃
And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.
Targum Jonathan on Leviticus
And the man who toucheth his bed shall wash his clothes, and wash himself in forty seahs of water, and shall be unclean until evening.
