'Uncleanness' in the Bible

And the priest hath caused her to swear, and hath said unto the woman, If no man hath lain with thee, and if thou hast not turned aside to uncleanness under thy husband, be free from these bitter waters which cause the curse;

Any one who is coming against the dead, against the body of man who dieth, and cleanseth not himself -- the tabernacle of Jehovah he hath defiled, and that person hath been cut off from Israel, for water of separation is not sprinkled upon him; he is unclean; his uncleanness is still upon him.
