'Bowels' in the Bible

And He saith unto me, 'Son of man, thy belly thou dost feed, and thy bowels thou dost fill with this roll that I am giving unto thee;' and I eat it, and it is in my mouth as honey for sweetness.

Their silver into out-places they cast, And their gold impurity becometh. Their silver and their gold is not able to deliver them, In a day of the wrath of Jehovah, Their soul they do not satisfy, And their bowels they do not fill, For the stumbling-block of their iniquity it hath been.
