Deuteronomy 9:16

13 And then the Lord said to me, I have seen that this people is stiff-necked:

14 Let me send destruction on them till their very name is cut off; and I will make of you a nation greater and stronger than they.

15 So turning round I came down from the mountain, and the mountain was burning with fire; and the two stones of the agreement were in my hands.

16 And I saw that you had done evil against the Lord, and had made for yourselves a metal image of a young ox: you had quickly been turned from the way in which the Lord had given you orders to go.

17 And I let the stones go from my hands, and they were broken before your eyes.

18 And I went down on my face before the Lord, as at the first, for forty days and forty nights, without taking food or drinking water, because of all your sin, in doing evil in the eyes of the Lord and moving him to wrath.

19 For I was full of fear because of the wrath of the Lord which was burning against you, with your destruction in view. But again the Lord's ear was open to my prayer.
