Levítico 18

No podrán casarse con su medio hermana, hija de la esposa de su padre;

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.
