'Impurity' in the Bible

But if she gives birth to a female child, then she shall be unclean for two weeks, as during her monthly period, and she shall remain [intimately separated] sixty-six days to be purified from the blood.

‘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.

If a man actually lies with her so that her menstrual impurity is on him, he shall be unclean for seven days; and every bed on which he lies 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.

Every bed on which she lies during the time of her discharge shall be to her like the bed of her menstrual impurity, and whatever she sits on shall be unclean, like the uncleanness of her monthly period.

and for the woman who is ill because of her monthly period, and for the one who has a discharge, whether man or woman, or for a man who lies with a woman who is [ceremonially] unclean.

If a man takes his brother’s wife, it is a hated and unclean thing; he has uncovered his brother’s nakedness. They will be childless.

Now a man who is [ceremonially] clean shall collect the ashes of the heifer and deposit them outside the camp in a clean place, and the congregation of the Israelites shall keep it for water to remove impurity; it is [to be used for] purification from sin.

That one shall purify himself from uncleanness with the water [made with the ashes of the burned heifer] on the third day and on the seventh day, and then he will be clean; but if he does not purify himself on the third day and on the seventh day, he will not be clean.

Whoever touches a corpse, the body of anyone who has died, and does not purify himself, defiles the tabernacle of the Lord; and that person shall be cut off from Israel [that is, excluded from the atonement made for them]. Because the water for impurity was not sprinkled on him, he shall be unclean; his uncleanness is still on him.

So it shall be a perpetual statute to them. He who sprinkles the water for impurity [on another] shall wash his clothes, and he who touches the water for impurity shall be unclean until evening.

everything that can stand fire, you shall pass through fire, and it shall be clean. Nevertheless, it shall also be purified with the water of purification [to remove its impurity]; and all that cannot stand fire [such as fabrics] you shall pass through water.

and does not eat [at the pagan shrines] on the mountains or raise his eyes to the idols of the house of Israel, or defile his neighbor’s wife or approach a woman during her [monthly] time of impurity—

“Son of man, when the house of Israel was living in their own land, they defiled it by their [own] behavior and by their [idolatrous] actions. Their conduct before Me was like the uncleanness of a woman during her [physical] impurity.

As for Ephraim, their glory will fly away like a bird;No birth, no pregnancy, and [because of their impurity] no conception.
