Deuteronomy 7:6-8

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.
