Mambo Ya Walawi 20:19

“ ‘Usikutane kimwili na dada wa mama yako wala wa baba yako, kwa maana hilo litamwaibisha jamaa wa karibu; ninyi wawili mtawajibika kwa ajili ya uovu huo.

And thou shalt not uncover the nakedness of thy mother’s sister, nor of thy father’s sister: for he uncovereth his near kin: they shall bear their iniquity.
