Exodus 32:15-18

15Then Moses turned and went down from the mountain with the two tablets of the Testimony in his hand; tablets that were written on both sides—they were written on one side and on the other.

16The tablets were the work of God; the writing was the writing of God engraved on the tablets.

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

18But Moses said, “It is not the sound of the cry of victory, Nor is it the sound of the cry of defeat; But I hear the sound of singing.”
