The empty vessel makes the loudest sound.

The saying is true, "The empty vessel makes the greatest sound

The empty vessel giveth a greater sound than the full barrel

What's the business, That such a hideous trumpet calls to parley The sleepers of the house? Speak, speak!

I did never know so full a voice issue from so empty a heart; but the saying is true, 'The empty vessel makes the greatest sound.'

Leave sound in an emptyhouse in its own room there. . . .
