Leviticus 18:7

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.

"'You shall not uncover the nakedness of your father, nor the nakedness of your mother: she is your mother. You shall not uncover her nakedness.

The nakedness of thy father, even the nakedness of thy mother, shalt thou not uncover: she is thy mother; thou shalt not uncover her nakedness.

`The nakedness of thy father and the nakedness of thy mother thou dost not uncover, she `is' thy mother; thou dost not uncover her nakedness.

You must not expose the nakedness of your father by having sexual relations with your mother. She is your mother; you must not have sexual relations with her.
