וְכָל־הַנֹּגֵ֖עַ בְּמִשְׁכָּבָ֑הּ יְכַבֵּ֧ס בְּגָדָ֛יו וְרָחַ֥ץ בַּמַּ֖יִם וְטָמֵ֥א עַד־הָעָֽרֶב׃
And whosoever toucheth her bed shall wash his clothes, and bathe himself in water, and be unclean until the even.
Leviticus
Anyone who touches any vessel that she sits on, shall wash his garments and bathe in water and is impure until the evening.
