Deuteronomy 9:16-18

And I looked, and behold, you had sinned against the LORD your God—had made for yourselves a molded calf! You had turned aside quickly from the way which the LORD had commanded you. Then I took the two tablets and threw them out of my two hands and broke them before your eyes. And I fell down before the LORD, as at the first, forty days and forty nights; I neither ate bread nor drank water, because of all your sin which you committed in doing wickedly in the sight of the LORD, to provoke Him to anger.
