Exodus 32:21-24

And Moses said unto Aaron, What did this people unto thee, that thou hast brought so great a sin upon them? And Aaron said, Let not the anger of my lord wax hot: thou knowest the people, that they are set on mischief. For they said unto me, Make us gods, which shall go before us: for as for this Moses, the man that brought us up out of the land of Egypt, we wot not what is become of him. And I said unto them, Whosoever hath any gold, let them break it off. So they gave it me: then I cast it into the fire, and there came out this calf.
