Exodus 32
2 Ref 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 Ref And all the people took the gold rings from their ears and gave them to Aaron.
4 Ref 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 Ref 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.
