Exodus 32:20-23

201He took the calf which they had made and burned it with fire, and ground it to powder, and scattered it over the surface of the water and made the sons of Israel drink it.

21Then Moses said to Aaron, “What did this people do to you, that you have brought such great sin upon them?” 22Aaron said, “Do not let the anger of my lord burn; you know the people yourself, 2that they are 3prone to evil. 23For 4they said to me, ‘Make 5a god for us who will go before us; for this Moses, the man who brought us up from the land of Egypt, we do not know what has become of him.’
