Exodus 32:19-20

19 It happened, as soon as he came near to the camp, that he saw the calf and the dancing: and Moses' anger grew hot, and he threw the tablets out of his hands, and broke them beneath the mountain.  20 He took the calf which they had made, and burnt it with fire, ground it to powder, and scattered it on the water, and made the children of Israel drink of it.
