Deuteronomy 9:15-18

So I turned and came down from the mountain, and the mountain was burning with fire. And the two tablets of the covenant were in my two hands. And I looked, and behold, you had sinned against the LORD your God. You had made yourselves a golden calf. You had turned aside quickly from the way that the LORD had commanded you. So I took hold of the two tablets and threw them out of my two hands and broke them before your eyes. Then I lay prostrate before the LORD as before, forty days and forty nights. I neither ate bread nor drank water, because of all the sin that you had committed, in doing what was evil in the sight of the LORD to provoke him to anger.
