Hebrew slaves in Babylonia changed the words and text to quotes from the Hebrew Scriptures that invoked God.
One bowl was inscribed with the “bill of divorce” from the devil and all of his monsters. It ordered demons to leave town.
How were these bowls used? They were turned upside down, and buried under the four cornerstones of buildings and houses.
