Deuteronomy 9:6

2 The people are strong and tall, the descendants of the Anakim. You know about them, and you have heard it said, “Who can stand up to the sons of Anak?”

3 But understand that today the LORD your God goes across ahead of you as a consuming fire; He will destroy them and subdue them before you. And you will drive them out and annihilate them swiftly, as the LORD has promised you.

4 When the LORD your God has driven them out before you, do not say in your heart, “Because of my righteousness the LORD has brought me in to possess this land.” Rather, the LORD is driving out these nations before you because of their wickedness.

5 It is not because of your righteousness or uprightness of heart that you are going in to possess their land, but it is because of their wickedness that the LORD your God is driving out these nations before you, to keep the promise He swore to your fathers, to Abraham, Isaac, and Jacob.

6 Understand, then, that it is not because of your righteousness that the LORD your God is giving you this good land to possess, for you are a stiff-necked people.

7 Remember this, and never forget how you provoked the LORD your God in the wilderness. From the day you left the land of Egypt until you reached this place, you have been rebelling against the LORD.

8 At Horeb you provoked the LORD, and He was angry enough to destroy you.

9 When I went up on the mountain to receive the tablets of stone, the tablets of the covenant that the LORD made with you, I stayed on the mountain forty days and forty nights. I ate no bread and drank no water.

10 Then the LORD gave me the two stone tablets, inscribed by the finger of God with the exact words that the LORD spoke to you out of the fire on the mountain on the day of the assembly.
