It is an accepted fact today that the state of the mind affects the body. This dissertation investigates the perception of the writers of the Hebrew Bible regarding the influence of emotions on body organs. By analyzing Hebrew expressions using body parts and verbs describing emotions, certain patterns appear. The heart, intestines, liver and kidneys were thought to be the seats of emotions; their biological functions were unimportant. The ancients knew that outside stimuli affected emotions, but not all emotions were described with body parts. Grief for a deceased and shame, for instance, were not. The most common emotion described using a restless body part is sorrow. Fermenting bowels, overturned heart, poured out liver, noises emitted from the body via the intestines and heart and a general malaise dwelling in the heart are symptoms of sorrow. A great cause for anxiety is illness. It is described as boiling intestines, sour heart and pierced kidneys. Fear alone, is described as a melting or soft heart. Other symptoms of fear described, which are confirmed by today's scientists, are trembling, feeling hurried, dropped hands, agitated stomach, facial pallor, shaking knees and control of bodily functions. Anger exists in the heart and nose alone causing the person to heat up. Compassion, love and longing only affect the intestines. The only positive emotions described with body parts are happiness and joy. These are described with verbs expressing happiness and singing rather than tremors. It is very clear that the biblical writers were keen observers of human behavior and expressed it in their work.
