Mambo Ya Walawi 20:9

“ ‘Ikiwa mtu yeyote atamlaani baba yake au mama yake, lazima auawe. Amemlaani baba yake au mama yake, nayo damu yake itakuwa juu ya kichwa chake mwenyewe.

¶ For every one that curseth his father or his mother shall be surely put to death: he hath cursed his father or his mother; his blood shall be upon him.
