Bible Verses About Idolatry: Often mixed up, with God's worship

When the people saw that Moshe was taking a long time to come down from the mountain, they gathered around Aharon and said to him, "Get busy; and make us gods to go ahead of us; because this Moshe, the man that brought us up from the land of Egypt - we don't know what has become of him."

Aharon said to them, "Have your wives, sons and daughters strip off their gold earrings; and bring them to me."

The people stripped off their gold earrings and brought them to Aharon.

He received what they gave him, melted it down, and made it into the shape of a calf. They said, "Isra'el! Here is your god, who brought you up from the land of Egypt!"

On seeing this, Aharon built an altar in front of it and proclaimed, "Tomorrow is to be a feast for ADONAI."
