Deuteronomy 7:1-10

“When the LORD your God brings you into the land you are about to enter and occupy, he will clear away many nations ahead of you: the Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites. These seven nations are greater and more numerous than you. When the LORD your God hands these nations over to you and you conquer them, you must completely destroy them. Make no treaties with them and show them no mercy. You must not intermarry with them. Do not let your daughters and sons marry their sons and daughters, for they will lead your children away from me to worship other gods. Then the anger of the LORD will burn against you, and he will quickly destroy you. This is what you must do. You must break down their pagan altars and shatter their sacred pillars. Cut down their Asherah poles and burn their idols. For you are a holy people, who belong to the LORD your God. Of all the people on earth, the LORD your God has chosen you to be his own special treasure. “The LORD did not set his heart on you and choose you because you were more numerous than other nations, for you were the smallest of all nations! Rather, it was simply that the LORD loves you, and he was keeping the oath he had sworn to your ancestors. That is why the LORD rescued you with such a strong hand from your slavery and from the oppressive hand of Pharaoh, king of Egypt. Understand, therefore, that the LORD your God is indeed God. He is the faithful God who keeps his covenant for a thousand generations and lavishes his unfailing love on those who love him and obey his commands. But he does not hesitate to punish and destroy those who reject him.
