Exodus 32:15-19

15Moses 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.

16The tablets were the work of God; the writing was the writing of God, engraved on the tablets.

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.
