Deuteronomy 7:6 - 7:8
6 For you are a holy people to Yahweh your God; Yahweh your God has chosen you to be a people for His own treasured possession out of all the peoples who are on the face of the earth. 7 “Yahweh did not set His affection on you nor choose you because you were more in number than any of the peoples, for you were the fewest of all peoples, 8 but because Yahweh loved you and kept the oath which He swore to your fathers, Yahweh brought you out with a strong hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt.
