וְאִשָּׁ֕ה אֲשֶׁ֨ר יִשְׁכַּ֥ב אִ֛ישׁ אֹתָ֖הּ שִׁכְבַת־זָ֑רַע וְרָחֲצ֣וּ בַמַּ֔יִם וְטָמְא֖וּ עַד־הָעָֽרֶב׃
The woman also with whom a man shall lie carnally, they shall both bathe themselves in water, and be unclean until the even.
Targum Jonathan on Leviticus
and secondly, a woman with whom a man lieth shall wash in forty seahs of water, and be unclean until evening.
