On the eighth day the flesh of the male child’s foreskin shall be circumcised. Then she shall remain [intimately separated] thirty-three days to be purified from the blood; she shall not touch any consecrated thing nor enter the [courtyard of the] sanctuary until the days of her purification are over. read more.

Also anything on which one of them falls after dying becomes unclean, whether it is an article of wood or clothing, or a skin, or a sack—any article that is used—it must be put in water, and will be unclean until the evening; then it becomes clean.
