Exodus 32:17-20

17When Joshua heard the noise of the people shouting, he said to Moses, “There is the sound of war in the camp.” 18Moses replied: “It is not the sound of victory, it is not the sound of defeat; it is the sound of singing that I hear.” 19When 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. 20And 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.
