I was arguing with a Documentary Hypothesis supporter who claimed that we consistently find that Biblical prohibitions and their punishments are not written in one place. The Ten Commandments are a clear case of a list of prohibitions, which punishments are scattered all over the following chapters.
For both views Talmudic views in Gittin 60, that Torah was given at once or chapter by chapter, I couldn't comprehend why would the Torah benefit from such an arrangement. Also for the statement that Torah is using human language, it's illogical to separate the two.
Do our sources speak of possible benefits of the separation between prohibitions and their corresponding punishments?
