'Calf' in the Bible

Then I saw how you had really sinned against the LORD your God! You had made for yourselves a calf, a cast idol. You had turned aside quickly from the way that the LORD your God had commanded.

Now, when you made the calf that made you sin, I grabbed it, burned it with fire, crushed it, and ground it thoroughly until it was pulverized to powder. Then I threw the powder into the river that was flowing from the mountain."
