Exodus 32:2-8

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!” Aaron, taking in the situation, built an altar before the calf. Aaron then announced, “Tomorrow is a feast day to GOD!” Early the next morning, the people got up and offered Whole-Burnt-Offerings and brought Peace-Offerings. The people sat down to eat and drink and then began to party. It turned into a wild party! GOD spoke to Moses, “Go! Get down there! Your people whom you brought up from the land of Egypt have fallen to pieces. In no time at all they’ve turned away from the way I commanded them: They made a molten calf and worshiped it. They’ve sacrificed to it and said, ‘These are the gods, O Israel, that brought you up from the land of Egypt!’”
