Hesabu 19:19

Mtu ambaye ni safi ndiye atakayemnyunyizia yeyote ambaye ni najisi siku ya tatu na siku ya saba, na katika siku ya saba atamtakasa mtu huyo. Mtu ambaye ametakaswa lazima afue nguo zake na kuoga kwa maji, na jioni ile atakuwa safi.

And the clean person shall sprinkle upon the unclean on the third day, and on the seventh day: and on the seventh day he shall purify himself, and wash his clothes, and bathe himself in water, and shall be clean at even.
