Exodus 32:3

1 And when the people saw that Moses was a long time coming down from the mountain, they all came to Aaron and said to him, Come, make us a god to go before us: as for this Moses, who took us up out of the land of Egypt, we have no idea what has become of him.

2 Then Aaron said to them, Take off the gold rings which are in the ears of your wives and your sons and your daughters, and give them to me.

3 And all the people took the gold rings from their ears and gave them to Aaron.

4 And he took the gold from them and, hammering it with an instrument, he made it into the metal image of a young ox: and they said, This is your god, O Israel, who took you out of the land of Egypt.

5 And when Aaron saw this, he made an altar before it, and made a public statement, saying, Tomorrow there will be a feast to the Lord.

6 So early on the day after they got up and made burned offerings and peace-offerings; and took their seats at the feast, and then gave themselves to pleasure.
