Deuteronomy 9:18-20

Then I flung myself down before GOD, just as I had at the beginning of the forty days and nights. I ate no food; I drank no water. I did this because of you, all your sins, sinning against GOD, doing what is evil in GOD’s eyes and making him angry. I was terrified of GOD’s furious anger, his blazing anger. I was sure he would destroy you. But once again GOD listened to me. And Aaron! How furious he was with Aaron—ready to destroy him. But I prayed also for Aaron at that same time.
