Deuteronomy 9:12, 16

Then the LORD told me, “Go down from here at once, because your people whom you brought out of Egypt have become corrupt. They have turned away quickly from what I commanded them and have made an idol for themselves.”

When I looked, I saw that you had sinned against the LORD your God; you had made for yourselves an idol cast in the shape of a calf. You had turned aside quickly from the way that the LORD had commanded you.
