Exodus 32:1-3

Now when the people saw that Moses delayed to come down from the mountain, the people assembled around Aaron and said to him, “Come, make us a god 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.”

Aaron said to them, “Tear off the gold rings which are in the ears of your wives, your sons, and your daughters, and bring them to me.”

So all the people tore off the gold rings which were in their ears and brought them to Aaron.
