Exodus 32:15-20

Then Moses turned and went down from the mountain with the two tablets of the Testimony in his hand; tablets that were written on both sides—they were written on one side and on the other. The tablets were the work of God; the writing was the writing of God engraved on the tablets. Now when Joshua heard the noise of the people as they shouted, he said to Moses, “There is a sound of battle in the camp.” But Moses 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.” And as soon as he approached the camp and he saw the calf and the dancing, Moses’ anger burned; and he threw the tablets from his hands and smashed them at the foot of the mountain. Then Moses took the calf they had made and burned it in the fire, and ground it to powder, and scattered it on the surface of the water and made the Israelites drink it.
