Exodus 32:4-7

He took the gold from the people and formed it with a tool and made a statue of a calf. Then the people said, “Israel, these are your gods who brought you out of the land of Egypt!” When Aaron saw all this, he built an altar before the calf and announced, “Tomorrow there will be a special feast to honor the LORD.” The people got up early the next morning and offered whole burnt offerings and fellowship offerings. They sat down to eat and drink, and then they got up and sinned sexually. Then the LORD said to Moses, “Go down from this mountain, because your people, the people you brought out of the land of Egypt, have ruined themselves.
