Deuteronomy 4:33-35

33Only you, the nation of Israel, have heard the voice of God that spoke to you from the middle of the fire. Only you have heard God speak and you still live!

34No other god has tried to rescue a nation from the power of another nation. The Lord your God did this for you when you were in Egypt. You saw how he used his great authority and strength to punish the Egyptians. He did powerful miracles. He brought war and disease that made them very afraid.

35The Lord has shown you all these things. So you know that he is the only true God. There is no other God.
