Deuteronomy 9:17-21

9:17 I grabbed the two tablets, threw them down, and shattered them before your very eyes. 9:18 Then I again fell down before the Lord for forty days and nights; I ate and drank nothing because of all the sin you had committed, doing such evil before the Lord as to enrage him. 9:19 For I was terrified at the Lord’s intense anger that threatened to destroy you. But he listened to me this time as well. 9:20 The Lord was also angry enough at Aaron to kill him, but at that time I prayed for him too. 9:21 As for your sinful thing that you had made, the calf, I took it, melted it down, ground it up until it was as fine as dust, and tossed the dust into the stream that flows down the mountain.
