Deuteronomy 4:33-35

4:33 Have a people ever heard the voice of God speaking from the middle of fire, as you yourselves have, and lived to tell about it? 4:34 Or has God ever before tried to deliver a nation from the middle of another nation, accompanied by judgments, signs, wonders, war, strength, power, and other very terrifying things like the Lord your God did for you in Egypt before your very eyes? 4:35 You have been taught that the Lord alone is God – there is no other besides him.
