Deuteronomy 9:22

18 Then I fell down before the LORD for forty days and forty nights, as I had done the first time. I did not eat bread or drink water because of all the sin you had committed in doing what was evil in the sight of the LORD and provoking Him to anger.

19 For I was afraid of the anger and wrath that the LORD had directed against you, enough to destroy you. But the LORD listened to me this time as well.

20 The LORD was angry enough with Aaron to destroy him, but at that time I also prayed for Aaron.

21 And I took that sinful thing, the calf you had made, and burned it in the fire. Then I crushed it and ground it to powder as fine as dust, and I cast it into the stream that came down from the mountain.

22 You continued to provoke the LORD at Taberah, at Massah, and at Kibroth-hattaavah.

23 And when the LORD sent you out from Kadesh-barnea, He said, “Go up and possess the land that I have given you.” But you rebelled against the command of the LORD your God. You neither believed Him nor obeyed Him.

24 You have been rebelling against the LORD since the day I came to know you.

25 So I fell down before the LORD for forty days and forty nights, because the LORD had said He would destroy you.

26 And I prayed to the LORD and said, “O Lord GOD, do not destroy Your people, Your inheritance, whom You redeemed through Your greatness and brought out of Egypt with a mighty hand.
