Deuteronomy 7:6-9

6For thou art an holy people to the LORD thy God: the LORD thy God hath chosen thee to be a special people to himself, above all people that are upon the face of the earth.

7The LORD did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people:

8But because the LORD loved you, and because he would keep the oath which he had sworn to your fathers, hath the LORD brought you out with a mighty hand, and redeemed you from the house of bondage, from the hand of Pharaoh king of Egypt.

9Know therefore that the LORD thy God, he is God, the faithful God, who keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;
