'Grinding' in the Bible

and your sin, which ye have made -- the calf -- I have taken, and I burn it with fire, and beat it, grinding well till that it is small as dust, and I cast its dust unto the brook which is going down out of the mount.

And the Philistines seize him, and pick out his eyes, and bring him down to Gaza, and bind him with two brazen fetters; and he is grinding in the prison-house.

And doors have been shut in the street. When the noise of the grinding is low, And one riseth at the voice of the bird, And all daughters of song are bowed down.
