Leviticus 15
31 Ref Thus shall ye separate the children of Israel from their uncleanness, that they die not in their uncleanness, when they defile my tabernacle that is in the midst of them.
32 Ref This is the law of him that hath an issue, and of him whose seed of copulation goeth from him, so that he is unclean thereby;
33 Ref and of her that is sick with her impurity, and of him that hath an issue, of the man, and of the woman, and of him that lieth with her that is unclean.
