Deuteronomy 7:6-9

6For you are a people holy to the Lord your God. He has chosen you to be his people, prized above all others on the face of the earth.

7It is not because you were more numerous than all the other peoples that the Lord favored and chose you – for in fact you were the least numerous of all peoples.

8Rather it is because of his love for you and his faithfulness to the promise he solemnly vowed to your ancestors that the Lord brought you out with great power, redeeming you from the place of slavery, from the power of Pharaoh king of Egypt.

9So realize that the Lord your God is the true God, the faithful God who keeps covenant faithfully with those who love him and keep his commandments, to a thousand generations,
