'Defiles' in the Bible

"'This is the law for cases of jealousy, when a wife, while under her husband's authority, goes astray and defiles herself,

"'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.

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.

"You must not pollute the land where you live, for blood defiles the land, and the land cannot be cleansed of the blood that is shed there, except by the blood of the person who shed it.
