Exodus 32:20-24

Then he took the calf which they had made and completely 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.

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

And Aaron said, “Do not let the anger of my lord burn; you know the people yourself, that they are prone to evil.

For they said to me, ‘Make a 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 happened to him.’

So I said to them, ‘Whoever has any gold, let them tear it off.’ Then they gave it to me, and I threw it into the fire, and out came this calf.”
