I was listening to a shiur and the rabbi said that Samuel knew Torah by the age of two. He didn't give any source for this, however.
Is there any source for what he said?
I have seen it alleged that Rav David Tzvi Hoffman disagrees with the Ramban's interpretation of Devarim 18:15, and would like to see details. Where can I find his commentary, so as to compare what he says and what Ramban says?
