I'm asking this as a general question. We do see in a few places that G-d speaks to Moshe and then, the Torah says something like, "Moshe told this to B'nai Yisra'el".
But, in numerous other places (seems common in the book of Vayikra, esp.) a paragraph begins וידבר ה אל משה לאמור (G-d spoke to Moshe to say..)
At what point did Moshe relay a set of commandments to the people? Should we assume that everything between one set of saying וידבר ה אל משה לאמור until its next appearance was said, or is there some other rule / method as to how to calculate this?
