'Son's' in the Bible

You may not have sex relations with your son's daughter or your daughter's daughter, for they are part of yourself;

Or with your daughter-in-law, for she is your son's wife, and you may not take her.

You may not take as wife a woman and her daughter, or her son's daughter or her daughter's daughter, for they are of one family: it is an act of shame.

And if a man has sex relations with his son's wife, the two of them are to be put to death: it is unnatural; their blood will be on them.
