'Grindeth' in the Bible

and he taketh the calf which they have made, and burneth it with fire, and grindeth until it is small, and scattereth on the face of the waters, and causeth the sons of Israel to drink.

and wheresoever it taketh him, it dasheth him down: and he foameth, and grindeth his teeth, and pineth away: and I spake to thy disciples that they should cast it out; and they were not able.
