'Rock' in the Bible

Take the belt that you bought and that is around your waist. Get up and go to the Euphrates, and hide it there in a crevice in the rock."

"Look, I'm against you, city dwelling in the valley, rock of the plain," declares the LORD, "those of you who say, "Who can come down against us and who can enter our habitations?'

"My message is like fire or like a hammer that shatters rock, is it not?" declares the LORD.

When you finish reading this scroll, tie a rock around it and throw it into the middle of the Euphrates.
