Exodus 32:15-20

Moses turned and went down the mountain with the two tablets of the covenant law in his hands. They were inscribed on both sides, front and back. The tablets were the work of God; the writing was the writing of God, engraved on the tablets. When Joshua heard the noise of the people shouting, he said to Moses, “There is the sound of war in the camp.” Moses replied: “It is not the sound of victory, it is not the sound of defeat; it is the sound of singing that I hear.” When Moses approached the camp and saw the calf and the dancing, his anger burned and he threw the tablets out of his hands, breaking them to pieces at the foot of the mountain. And he took the calf the people had made and burned it in the fire; then he ground it to powder, scattered it on the water and made the Israelites drink it.
