Deuteronomy 9:17-21

So I took hold of the two tablets and threw them from my two hands, and smashed them to pieces before your eyes!

Then I fell down before the Lord like the first time, for forty days and nights; I neither ate bread nor drank water, because of all your sin which you had committed by doing what was evil in the sight of the Lord, to provoke Him to anger.

For I was afraid of the anger and the rage with which the Lord was angry with you so as to destroy you; but the Lord listened to me that time as well.

The Lord was also angry enough with Aaron to destroy him; so I also prayed for Aaron at the same time.

And I took your sinful thing which you had made, the calf, and burned it in the fire and crushed it, grinding it thoroughly until it was as fine as dust; and I threw its dust into the stream that came down from the mountain.
