Exodus 32:15-20

15Then Moses turned and went down the mountain with the two tablets of the Testimony in his hands. They were inscribed on both sides, front and back. 16The tablets were the work of God, and the writing was the writing of God, engraved on the tablets.

17When Joshua heard the sound of the people shouting, he said to Moses, “The sound of war is in the camp.”

18But Moses replied:

19As Moses approached the camp and saw the calf and the dancing, he burned with anger and threw the tablets out of his hands, shattering them at the base of the mountain. 20Then he took the calf they had made, burned it in the fire, ground it to powder, and scattered the powder over the face of the water. Then he forced the Israelites to drink it.
