'Bellies' in the Bible

But [when] they went into their bellies it could not be known that they went into their bellies, for their appearance [was] as ugly as at the beginning. Then I awoke.

With Your hand, Lord, save me from men,from men of the worldwhose portion is in this life:You fill their bellies with what You have in store;their sons are satisfied,and they leave their surplus to their children.

For we lie in the dirt, with our bellies pressed to the ground.
