Exodus 32:2-4, 24

So Aaron told them, “Take off the gold rings from the ears of your wives and sons and daughters and bring them to me.” They all did it; they removed the gold rings from their ears and brought them to Aaron. He took the gold from their hands and cast it in the form of a calf, shaping it with an engraving tool. The people responded with enthusiasm: “These are your gods, O Israel, who brought you up from Egypt!”

“So I said, ‘Who has gold?’ And they took off their jewelry and gave it to me. I threw it in the fire and out came this calf.”
