There is a verse that is often taken to mean something it does not say. אתה הראתה לדעת כי השם הוא האלהים אין עוד מלבדו. "You were shown to know that the Lord is God, there is none other besides Him." Which means: There is no other god besides God, the First Cause. The reason I say this is two fold. One is simple grammar. If the words "אין עוד מלבדו" would be by themselves in the verse, then that would perhaps be different. However in the context of the verse, the meaning is the Lord is God, there is no other god besides Him.

The other reason I say this is in the actual meaning of the verse. In that verse in Deuteronomy Moses is talking to Klal Israel and telling them you were shown at Mount Sinai to see and to know something. What was that? That was that the Lord is the true God and there is no other gods besides Him. That is the simple explanation of what Israel saw at Mount Sinai. Not that there were shown that there is nothing. 

The basic idea of the Torah is that God created the world from nothing. Ex Nihilo. And all Rishonim agree that that is the point of Torah.
