'Defiles' in the Bible

"'If any man dies very suddenly beside him, and he defiles the head of his separation; then he shall shave his head in the day of his cleansing. On the seventh day he shall shave it.

Whoever touches a dead person, the body of a man who has died, and doesn't purify himself, defiles the tabernacle of Yahweh; and that soul shall be cut off from Israel: because the water for impurity was not sprinkled on him, he shall be unclean; his uncleanness is yet on him.
