'Bowels' in the Bible

He said to me, Son of man, cause your belly to eat, and fill your bowels with this scroll that I give you. Then I ate it; and it was as sweet as honey in my mouth.

They shall cast their silver in the streets, and their gold shall be as an unclean thing; their silver and their gold shall not be able to deliver them in the day of the wrath of Yahweh: they shall not satisfy their souls, neither fill their bowels; because it has been the stumbling block of their iniquity.
