Deuteronomy 9:16
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.
Deuteronomy 9:21
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.
