Deuteronomy 4:35-40

To you it was shown that you might know that the LORD, He is God; there is no other besides Him. Out of the heavens He let you hear His voice to discipline you; and on earth He let you see His great fire, and you heard His words from the midst of the fire. Because He loved your fathers, therefore He chose their descendants after them. And He personally brought you from Egypt by His great power, driving out from before you nations greater and mightier than you, to bring you in and to give you their land for an inheritance, as it is today. Know therefore today, and take it to your heart, that the LORD, He is God in heaven above and on the earth below; there is no other. So you shall keep His statutes and His commandments which I am giving you today, that it may go well with you and with your children after you, and that you may live long on the land which the LORD your God is giving you for all time.”
