Exodus 32:15-19

15Then Moses turned and went down the mountain with the two tablets of the testimony in his hands. They were inscribed on both sides — inscribed front and back.

16The tablets were the work of God, and the writing was God’s writing, engraved on the tablets.

17When Joshua heard the sound of the people as they shouted, he said to Moses, “There is a sound of war in the camp.”

18But Moses replied, It’s not the sound of a victory cry and not the sound of a cry of defeat; I hear the sound of singing!

19As he approached the camp and saw the calf and the dancing, Moses became enraged and threw the tablets out of his hands, smashing them at the base of the mountain.
