Leviticus 15:19-31 NASB1995
‘When a woman has a discharge, if her discharge in her body is blood, she shall continue in her menstrual impurity for seven days; and whoever touches her shall be unclean until evening. Everything also on which she lies during her menstrual impurity shall be unclean, and everything on which she sits shall be unclean. Anyone who touches her bed shall wash his clothes and bathe in water and be unclean until evening. Whoever touches any thing on which she sits shall wash his clothes and bathe in water and be unclean until evening. Whether it be on the bed or on the thing on which she is sitting, when he touches it, he shall be unclean until evening. If a man actually lies with her so that her menstrual impurity is on him, he shall be unclean seven days, and every bed on which he lies shall be unclean.
‘Now if a woman has a discharge of her blood many days, not at the period of her menstrual impurity, or if she has a discharge beyond that period, all the days of her impure discharge she shall continue as though in her menstrual impurity; she is unclean. Any bed on which she lies all the days of her discharge shall be to her like her bed at menstruation; and every thing on which she sits shall be unclean, like her uncleanness at that time. Likewise, whoever touches them shall be unclean and shall wash his clothes and bathe in water and be unclean until evening. When she becomes clean from her discharge, she shall count off for herself seven days; and afterward she will be clean. Then on the eighth day she shall take for herself two turtledoves or two young pigeons and bring them in to the priest, to the doorway of the tent of meeting. The priest shall offer the one for a sin offering and the other for a burnt offering. So the priest shall make atonement on her behalf before the LORD because of her impure discharge.’
“Thus you shall keep the sons of Israel separated from their uncleanness, so that they will not die in their uncleanness by their defiling My tabernacle that is among them.”
