'Calf' in the Bible

I looked, and behold, you had sinned against Yahweh your God; you had made yourselves a molten calf: you had turned aside quickly out of the way which Yahweh had commanded you.

I took your sin, the calf which you had made, and burnt it with fire, and stamped it, grinding it very small, until it was as fine as dust: and I cast its dust into the brook that descended out of the mountain.
