Any bed on which she lies or any furniture on which she sits during the days of her discharge will be unclean, like her bed during her menstrual period.
KJV
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.
ASV
Every bed whereon she lieth all the days of her issue shall be unto her as the bed of her impurity: and everything whereon she sitteth shall be unclean, as the uncleanness of her impurity.
