Deuteronomy 9:12-16, 21

And the LORD said unto me, Arise, get thee down quickly from hence; for thy people which thou hast brought forth out of Egypt have corrupted themselves; they are quickly turned aside out of the way which I commanded them; they have made them a molten image. Furthermore the LORD spake unto me, saying, I have seen this people, and, behold, it is a stiffnecked people: let me alone, that I may destroy them, and blot out their name from under heaven: and I will make of thee a nation mightier and greater than they. So I turned and came down from the mount, and the mount burned with fire: and the two tables of the covenant were in my two hands. And I looked, and, behold, ye had sinned against the LORD your God, and had made you a molten calf: ye had turned aside quickly out of the way which the LORD had commanded you.

And I took your sin, the calf which ye had made, and burnt it with fire, and stamped it, and ground it very small, even until it was as small as dust: and I cast the dust thereof into the brook that descended out of the mount.
