Deuteronomy 9:18-20 WEB

18 I fell down before Yahweh, as at the first, forty days and forty nights; I did neither eat bread nor drink water; because of all your sin which you sinned, in doing that which was evil in the sight of Yahweh, to provoke him to anger. 19 For I was afraid of the anger and hot displeasure, with which Yahweh was angry against you to destroy you. But Yahweh listened to me that time also. 20 Yahweh was very angry with Aaron to destroy him: and I prayed for Aaron also at the same time.
