Deuteronomy 10:20-22

Respect the LORD your God and serve him. Be loyal to him and make your promises in his name. He is the one you should praise; he is your God, who has done great and wonderful things for you, which you have seen with your own eyes. There were only seventy of your ancestors when they went down to Egypt, and now the LORD your God has made you as many as the stars in the sky.
