Exodus 32:15-19

15Moses left the Lord and he went down the mountain. He carried in his hands the two flat stones with God's special commands on them. God had written his commands on both sides of the stones.

16This was God's own work. He himself had written the words on the stones.

17Joshua heard the noise of the Israelites as they were shouting down below. He said to Moses, ‘I can hear the sound of war in the camp!’

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.
