Leviticus Chapter 16 Verse 2And the LORD said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy [place] within the vail before the mercy seat, which [is] upon the ark; that he die not: for I will appear in the cloud upon the mercy seat.

And if a woman have an issue of her blood many days out of the time of her separation, or if it run beyond the time of her separation; all the days of the issue of her uncleanness shall be as the days of her separation: she [shall be] unclean.

Every bed whereon she lieth all the days of her issue shall be unto her as the bed of her separation: and whatsoever she sitteth upon shall be unclean, as the uncleanness of her separation.

But if she be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean.

And on the eighth day she shall take unto her two turtles, or two young pigeons, and bring them unto the priest, to the door of the tabernacle of the congregation.

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] among them.

This [is] the law of him that hath an issue, and [of him] whose seed goeth from him, and is defiled therewith;

And of her that is sick of her flowers, and of him that hath an issue, of the man, and of the woman, and of him that lieth with her that is unclean.

And the LORD spake unto Moses after the death of the two sons of Aaron, when they offered before the LORD, and died;

Thus shall Aaron come into the holy [place]: with a young bullock for a sin offering, and a ram for a burnt offering.

He shall put on the holy linen coat, and he shall have the linen breeches upon his flesh, and shall be girded with a linen girdle, and with the linen mitre shall he be attired: these [are] holy garments; therefore shall he wash his flesh in water, and [so] put them on.

And he shall take of the congregation of the children of Israel two kids of the goats for a sin offering, and one ram for a burnt offering.
