Old Testament and the Truth

I became fascinated with the history of the Old Testament when I read about Ezra and his reading of the Torah scroll from daybreak to noon. I realized that it would be an impossibility to do that with today's Torah, the Old Testament. My curiosity was aroused further when I learned about the lack of discussion regarding the change. Who authored the inclusion of additional material and who authorized it? What was the purpose and what exactly was added and when? Many questions without rational answers. My brother and I discussed the matter and he suggested that I start with Egyptian hieroglyphics, picture writing, and trace the history of written Hebrew. I have done that and the transition from cuneiform clay tablets to the meaning of the Hebrew signs has been revealing. The revelation of the effect of the Babylonian Exile on Judaism and the Old Testament, in particular, has not been revealed until now. The truth about the Old Testament, the Torah, will finally be revealed
