Leviticus 15:26

Every bed whereon she lieth all the days of her issue shall
be unto her as the bed of her separation
As defiled and as defiling as that, ( Leviticus 15:20 Leviticus 15:21 ) ; and whatsoever she sitteth upon shall be unclean, as the uncleanness
of her separation;
as such were when she was in that condition, see ( Leviticus 15:20 ) .
