Anyone who touches the corpse of any dead person and does not purify himself defiles the tabernacle of the Lord. And that person must be cut off from Israel, because the water of purification was not sprinkled on him. He will be unclean; his uncleanness remains on him.
“‘If anyone dies very suddenly beside him and he defiles his consecrated head, then he must shave his head on the day of his purification – on the seventh day he must shave it.
It happened that some men who were ceremonially defiled by the dead body of a man could not keep the Passover on that day, so they came before Moses and before Aaron on that day.
