'Unclean' in the Bible

But there were some men who were unclean because of a human corpse, so they could not observe the Passover on that day. These men came before Moses and Aaron the same day

and said to him, “We are unclean because of a human corpse. Why should we be excluded from presenting the Lord’s offering at its appointed time with the other Israelites?”

“Tell the Israelites: When any one of you or your descendants is unclean because of a corpse or is on a distant journey, he may still observe the Passover to the Lord.

The firstborn of every living thing, man or animal, presented to the Lord belongs to you. But you must certainly redeem the firstborn of man, and redeem the firstborn of an unclean animal.

Then the priest must wash his clothes and bathe his body in water; after that he may enter the camp, but he will remain ceremonially unclean until evening.

The one who burned the cow must also wash his clothes and bathe his body in water, and he will remain unclean until evening.

Then the one who gathers up the cow’s ashes must wash his clothes, and he will remain unclean until evening. This is a permanent statute for the Israelites and for the foreigner who resides among them.

“The person who touches any human corpse will be unclean for seven days.

Anyone who touches a body of a person who has died, and does not purify himself, defiles the tabernacle of the Lord. That person will be cut off from Israel. He remains unclean because the water for impurity has not been sprinkled on him, and his uncleanness is still on him.

“This is the law when a person dies in a tent: everyone who enters the tent and everyone who is already in the tent will be unclean for seven days,

and any open container without a lid tied on it is unclean.

Anyone in the open field who touches a person who has been killed by the sword or has died, or who even touches a human bone, or a grave, will be unclean for seven days.

For the purification of the unclean person, they are to take some of the ashes of the burnt sin offering, put them in a jar, and add fresh water to them.

“The one who is clean is to sprinkle the unclean person on the third day and the seventh day. After he purifies the unclean person on the seventh day, the one being purified must wash his clothes and bathe in water, and he will be clean by evening.

But a person who is unclean and does not purify himself, that person will be cut off from the assembly because he has defiled the sanctuary of the Lord. The water for impurity has not been sprinkled on him; he is unclean.

This is a permanent statute for them. The person who sprinkles the water for impurity is to wash his clothes, and whoever touches the water for impurity will be unclean until evening.

Anything the unclean person touches will become unclean, and anyone who touches it will be unclean until evening.”

Do not make the land unclean where you live and where I reside; for I, Yahweh, reside among the Israelites.”
