Leviticus 15:28

²⁶And 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.

²⁷Every one that touches it shall be unclean; and he shall wash his garments, and bathe his body in water, and shall be unclean till evening.

— Leviticus 15:28 —

²⁹And on the eighth day she shall take two turtledoves, or two young pigeons, and shall bring them to the priest, to the door of the tabernacle of witness.

³⁰And the priest shall offer one for a sin offering, and the other for a whole burnt offering, and the priest shall make atonement for her before the Lord for her unclean flux.
