The Code of Hammurabi
English, translated by C. H. W. Johns — Johns, The Oldest Code of Laws in the World, Edinburgh, 1903
If a son of a palace warder, or of a vowed woman, to the father that brought him up, and the mother that brought him up, has said 'thou art not my father, thou art not my mother,' one shall cut out his tongue.
