The law against sexual intimacy with a woman during her menstrual cycle was outlined in Leviticus 15:19, Leviticus 15:24. The punishment for both the man and his wife is that they shall be cut off from the nation of Israel. This signifies that they shall be excommunicated from the community.
18 Si un homme couche avec une femme qui a son indisposition, et découvre sa nudité, s'il découvre son flux, et qu'elle découvre le flux de son sang, ils seront tous deux retranchés du milieu de leur peuple.
