Deuteronomy 7:6-9

6For thou art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a peculiar people unto himself, above all peoples 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 peoples:

8but because the LORD loveth you, and because he would keep the oath which he sware unto your fathers, hath the LORD brought you out with a mighty hand, and redeemed you out of 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, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;
