Numbers 19:20

“Thus you shall keep the sons of Israel separated from their uncleanness, so that they will not die in their uncleanness by making My tabernacle that is among them unclean.”

“But if he does not wash them or bathe his body, then he shall bear his guilt.”

‘All the days of his dedication as a Nazirite to Yahweh he shall not go near to a dead person.

“Thus you shall do to them, for their cleansing: sprinkle purifying water on them, and let them use a razor over their whole body and wash their clothes, and they will be clean.

But there were some men who were unclean because of a dead person, so that they could not celebrate Passover on that day; so they came near before Moses and Aaron on that day.

‘Anyone who touches a corpse, the body of a man who has died, and does not purify himself, makes the tabernacle of Yahweh unclean; and that person shall be cut off from Israel. Because the water for impurity was not splashed on him, he shall be unclean; his uncleanness is still on him.

“And you, camp outside the camp seven days; whoever has killed any person and whoever has touched any slain, purify yourselves, you and your captives, on the third day and on the seventh day.

Thus He will sprinkle many nations, Kings will shut their mouths on account of Him; For what had not been told them they will see, And what they had not heard they will understand.
