So we see that in the New Testament it was the language of the day to describe someone as being possessed with demons if they were mentally ill or had a disease which no one understood.
Basi tunaona kwamba katika Agano Jipya ulikuwa ni msemo wa siku zile wa kusema mtu mwingine kuwa ana pepo ikiwa walikuwa wagonjwa wa akili au walikuwa na ugonjwa ambao hakuna aliyeufahamu.
