In the Old Testament explicit medical advice was not usually given (except for applying a poultice of figs to Hezekiah’s boil), but the laws on clean and unclean can be seen to be very sanitary.
Kwenye Agano la Kale mashauri ya moja kwa moja ya tiba hayakutolewa kwa kawaida (isipokuwa kutumia mkuyu wa moto kutibu jipu la tumboni mwa Hezekia), lakini sheria za vitu visafi na vitu najisi zinaonyesha kuwa za kiafya hasa.
