Exodus 32:17-19

32:17 When Joshua heard the noise of the people as they shouted, he said to Moses, “It is the sound of war in the camp!” 32:18 Moses said, “It is not the sound of those who shout for victory, nor is it the sound of those who cry because they are overcome, but the sound of singing I hear.”

32:19 When he approached the camp and saw the calf and the dancing, Moses became extremely angry. He threw the tablets from his hands and broke them to pieces at the bottom of the mountain.
