"'If a woman has a discharge, and her discharge in her flesh is blood, she shall be in her impurity seven days: and whoever touches her shall be unclean until the evening.
"'If a man lies with a woman having her monthly period, and uncovers her nakedness; he has made naked her fountain, and she has uncovered the fountain of her blood: and both of them shall be cut off from among their people.
In you have they uncovered their fathers' nakedness; in you have they humbled her who was unclean in her impurity.
