'Defiles' in the Bible

‘This is the law of jealousy: when a wife, being under the authority of her husband, goes astray and defiles herself,

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