With reference to bigamy with mother and daughter the law reads (Lev. 20:14): "It is wickedness" ("Zimmah hi"), and because elsewhere (Lev. 18:17) the identical expression is used with reference to criminal conversation of man with female relatives of other degrees, by Gezerah shawah, the penalty which the Pentateuch attaches to the former also attaches to the latter. On the same principle the penalty is established for such conversation with relatives within certain ascending degrees, comparing them with the descending degrees of like removes explicitly mentioned in the Bible.
