Levítico 18

Non ti congiungerai colla figlia della moglie del padre tuo, cui questa partorì al padre tuo, ond'ella è tua sorella.

La desnudez de la hija de la mujer de tu padre, engendrada de tu padre, tu hermana es, su desnudez no descubrirás.

The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.

“‘You shall not uncover the nakedness of your father’s wife’s daughter, conceived by your father, since she is your sister.
