Leviticus 15:26

And every bed on which she shall lie all the days of her flux shall be to her as the bed of her separation, and every seat whereon she shall sit shall be unclean according to the uncleanness of her separation.

Every bed whereon she lieth all the days of her issue shall be unto her as the bed of her separation: and whatsoever she sitteth upon shall be unclean, as the uncleanness of her separation.

Every bed she lies on all the days of her discharge shall be to her as the bed of her period. Everything she sits on shall be unclean, as the uncleanness of her period.
