'Separation' in the Bible

‘When a woman has a discharge, if her bodily discharge is blood, she shall continue in her menstrual impurity for seven days; and whoever touches her shall be unclean until evening.

Everything on which she lies during her menstrual impurity shall be unclean; and everything on which she sits shall be unclean.

‘Now if a woman has a flow of blood for many days, not during the time of her menstruation, or if she has a discharge beyond that period, as long as the impure discharge continues she shall be as she is in the days of her [normal] menstrual impurity; she is unclean.

The goat shall carry on itself all their (the Israelites) wickedness, carrying them to a solitary (infertile) land; and he shall release the goat in the wilderness.
