In Old Testament times, an evil or unclean spirit referred to a troubled mental state (Jud.9:23; 1 Sam.16:14; 18:10). In New Testament times, the language of evil spirit/ demon possession had come to refer to those suffering mental illness.
Kwa nyakati za Agano la Kale, Roho mbaya au mchafu ilikuwa inatajwa hali ya akili iliyotaabika (Amu. 9: 23; 1 Sam. 16:14; 18: 10). Kwa nyakati za Agano Jipya, msemo wa roho chafu / kupagawa na pepo ulifikia kuwasema waliokuwa wanasumbuliwa na maradhi ya akili.
