Deuteronomy 9:17

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.

And I fell down before the LORD, as at the first, forty days and forty nights: I did neither eat bread, nor drink water, because of all your sins which ye sinned, in doing wickedly in the sight of the LORD, to provoke him to anger.
