Exodus 32:16-20

The tablets were God’s work, and the writing was God’s writing engraved on the tablets.

Now when Joshua heard the sound of the people as they shouted, he said to Moses, “There is a sound of war in the camp.”

But he said, “It is not the sound of the cry of victory, Nor is it the sound of the cry of defeat; But I hear the sound of singing.” Moses’ Anger

And it came about, as soon as Moses approached the camp, that he saw the calf and the people dancing; and Moses’ anger burned, and he threw the tablets from his hands and shattered them to pieces at the foot of the mountain.

Then he took the calf which they had made and completely burned it with fire, and ground it to powder, and scattered it over the surface of the water and made the sons of Israel drink it.
