'Uncover Her Nakedness' in the Bible
The nakedness of thy father, or the nakedness of thy mother, shalt thou not uncover: she is thy mother, thou shalt not uncover her nakedness.
The nakedness of thy father's wife's daughter, begotten by thy father, (she is thy sister) thou shalt not uncover her nakedness.
Thou shalt not uncover the nakedness of thy daughter-in-law: she is thy son's wife, thou shalt not uncover her nakedness.
Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.
Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness besides the other in her life-time.
Also thou shalt not approach to a woman to uncover her nakedness, as long as she is put apart for her uncleanness.
And if a man shall lie with a woman having her sickness, and shall uncover her nakedness; he hath discovered her fountain, and she hath uncovered the fountain of her blood: and both of them shall be cut off from among their people.
