Exodus 32:15-18

15And Moses turned and went down from the mountain, and the two tablets of the Testimony were in his hand. The tablets were written on both sides; on the one side and on the other they were written.

16Now the tablets were the work of God, and the writing was the writing of God engraved on the tablets.

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

18But he said: “It is not the noise of the shout of victory, Nor the noise of the cry of defeat, But the sound of singing I hear.”
