Exodus 32:4-5 ▼

4 Then Aaron took the gold, melted it down, and molded it into the shape of a calf. When the people saw it, they exclaimed, “O Israel, these are the gods who brought you out of the land of Egypt!”

5 Aaron saw how excited the people were, so he built an altar in front of the calf. Then he announced, “Tomorrow will be a festival to the LORD!”
