Exodus 32:1–6
32 And the people saw that Moses delayed to come down from the mountain, and the people gathered opposite Aaron, and they said to him, “Come,a make for us gods who will go before us, because this Moses, the man who brought us up from the land of Egypt, we do not know what has become of him.”
2 And Aaron said to them, “Take off the rings of gold that are on the ears of your wives, your sons, and your daughters, and bring it to me.” 3 And all the people took off the rings of gold that were on their ears and brought it to Aaron. 4 And he took from their hand, and he shaped it with a tool, and he made it a cast-image bull calf, and they said, “These are your gods, Israel, who brought you up from the land of Egypt.”
5 And Aaron saw, and he built an altar before it, and Aaron called, and he said, “A feast for Yahweh tomorrow.” 6 And they started early the next day, and they offered burnt offerings, and they presented fellowship offerings, and the people sat to eat and drink, and they rose up to revel.
