'Son's' in the Bible

"'You shall not uncover the nakedness of your son's daughter, or of your daughter's daughter, even their nakedness: for theirs is your own nakedness.

"'You shall not uncover the nakedness of your daughter-in-law: she is your son's wife. You shall not uncover her nakedness.

"'You shall not uncover the nakedness of a woman and her daughter. You shall not take her son's daughter, or her daughter's daughter, to uncover her nakedness; they are near kinswomen: it is wickedness.
