Deutronomy 9:4-6
Reminder: Why God chose Israel?
Hear, Israel: You are now about to cross the Jordan to go in and dispossess nations greater and stronger than you, with large cities that have walls up to the sky. The people are strong and tall—Anakites! You know about them and have heard it said: “Who can stand up against the Anakites?” But be assured today that the Lord your God is the one who goes across ahead of you like a devouring fire. He will destroy them; he will subdue them before you. And you will drive them out and annihilate them quickly, as the Lord has promised you. After the Lord your God has driven them out before you, do not say to yourself, “The Lord has brought me here to take possession of this land because of my righteousness.” No, it is on account of the wickedness of these nations that the Lord is going to drive them out before you. It is not because of your righteousness or your integrity that you are going in to take possession of their land; but on account of the wickedness of these nations, the Lord your God will drive them out before you, to accomplish what he swore to your fathers, to Abraham, Isaac and Jacob. 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. Remember this and never forget how you aroused the anger of the Lord your God in the wilderness. From the day you left Egypt until you arrived here, you have been rebellious against the Lord . At Horeb you aroused the Lord ’s wrath so that he was angry enough to destroy you. When I went up on the mountain to receive the tablets of stone, the tablets of the covenant that the Lord had made with you, I stayed on the mountain forty days and forty nights; I ate no bread and drank no water. The Lord gave me two stone tablets inscribed by the finger of God. On them were all the commandments the Lord proclaimed to you on the mountain out of the fire, on the day of the assembly.
