Deuteronomy 10:20-22

10:20 Revere the Lord your God, serve him, be loyal to him and take oaths only in his name. 10:21 He is the one you should praise; he is your God, the one who has done these great and awesome things for you that you have seen. 10:22 When your ancestors went down to Egypt, they numbered only seventy, but now the Lord your God has made you as numerous as the stars of the sky.
