Levítico 18

A nudez da filha da mulher de teu pai, gerada de teu pai, tua irmã é, sua nudez não descobrirás.

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.
