Exodus 32:18-19

18But Moses said, ‘It is not the noise that soldiers make when they have won a battle. It is not the sound of soldiers who are crying because their enemy has won against them. I can hear the sound of people who are singing.’

19Then Moses arrived at the camp. He saw the gold calf. He saw that the people were dancing. He became very angry. He threw the two flat stones that he was carrying onto the ground. He broke them into pieces there at the bottom of the mountain.
