What does Deuteronomy 9:17 mean?

Leave me alone, that I may destroy them, and blot out their name from under the sky; and I will make of you a nation mightier and greater than they.”

So I turned and came down from the mountain, and the mountain was burning with fire. The two tablets of the covenant were in my two hands.

I looked, and behold, you had sinned against Yahweh your God. You had made yourselves a molten calf. You had quickly turned away from the way which Yahweh had commanded you.

I fell down before Yahweh, as at the first, forty days and forty nights. I neither ate bread nor drank water, because of all your sin which you sinned, in doing that which was evil in Yahweh’s sight, to provoke him to anger.

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.

Yahweh was angry enough with Aaron to destroy him. I prayed for Aaron also at the same time.
