Levítico 18

And, a woman unto her sister, shalt thou not take,—to cause rivalry, by uncovering her shame besides her own while she is living.

No tomarás mujer juntamente con su hermana, para hacerla su rival, descubriendo su desnudez delante de ella en su vida.

Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.

“‘You shall not take a wife in addition to her sister, to be a rival, to uncover her nakedness, while her sister is still alive.
