Exodus 34:9

6 And the Lord went past before his eyes, saying, The Lord, the Lord, a God full of pity and grace, slow to wrath and great in mercy and faith;

7 Having mercy on thousands, overlooking evil and wrongdoing and sin; he will not let wrongdoers go free, but will send punishment on children for the sins of their fathers, and on their children's children to the third and fourth generation.

8 Then Moses quickly went down on his face in worship.

9 And he said, If now I have grace in your eyes, let the Lord go among us, for this is a stiff-necked people, and give us forgiveness for our wrongdoing and our sin, and take us for your heritage.

10 And the Lord said, See, this is what I will undertake: before the eyes of your people I will do wonders, such as have not been done in all the earth or in any nation: and all your people will see the work of the Lord, for what I am about to do for you is greatly to be feared.

11 Take care to do the orders which I give you today; I will send out from before you the Amorite and the Canaanite and the Hittite and the Perizzite and the Hivite and the Jebusite.

12 But take care, and do not make any agreement with the people of the land where you are going, for it will be a cause of sin to you.
