It seems significant that the word "demons" only occurs four times in the Old Testament and always describes idol worship, but it occurs many times in the Gospel records. We suggest this is because, at the time the Gospels were written, it was the language of the day to say that any disease that could not be understood was the fault of demons.
Ni jambo la maana kujua kwamba Neno'pepo’ linaonekana kutokeza mara nne katika Agano la Kale na daima laelezea kutumikia sanamu, bali limetokea mara nyingi katika taarifa za Injili. Tunadokeza hii ni kwa sababu, wakati Injili zilipokuwa zikiandikwa, ulikuwa ni msemo wa siku zile kuusema ugonjwa wowote ambao haukufahamika ulikuwa ni sababu ya mapepo.
