Exodus 32:20-23

20Then he took the calf which they had made, burned it in the fire, and ground it to powder; and he scattered it on the water and made the children of Israel drink it.

21And Moses said to Aaron, “What did this people do to you that you have brought so great a sin upon them?”

22So Aaron said, “Do not let the anger of my lord become hot. You know the people, that they are set on evil.

23For they said to me, ‘Make us gods that shall go before us; as for this Moses, the man who brought us out of the land of Egypt, we do not know what has become of him.’
