'Stomach' in the Bible

For this reason my stomach churns; cramps overwhelm me like the contractions of a woman in labor. I am disturbed by what I hear, horrified by what I see.

It will be like a hungry man dreaming that he is eating, only to awaken and find that his stomach is empty. It will be like a thirsty man dreaming that he is drinking, only to awaken and find that he is still weak and his thirst unquenched. So it will be for the horde from all the nations that fight against Mount Zion.
