Verse 12

And Judah said unto him, Surely if I this day open my mouth against thee I would swallow thee up that thou be destroyed from off the earth and perish this day from thy kingdom. And Joseph said, Surely if thou openest thy mouth I have power and might to close thy mouth with a stone until thou shalt not be able to utter a word; see how many stones are before us, truly I can take a stone, and force it into thy mouth and break thy jaws.
