'Defiles' in the Bible

“This is the law regarding jealousy when a wife goes astray and defiles herself while under her husband’s authority,

‘But if a man dies very suddenly beside him and he defiles his dedicated head of hair, then he shall shave his head on the day when he becomes clean; he shall shave it on the seventh day.

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.

“Do not defile the land where you are, for bloodshed defiles the land, and there can be no atonement for the land because of the blood that is shed on it, except by the blood of the person who shed it.
