positive commandments

"Swearing in G-d's name"

It's intriguing to see how the commentators dispute what seems to be a simple verse in parashat Eikev, Deuteronomy 10:20, that states "and by His name shall you swear." Maimonides sees it as a positive mitzvah, Nachmanides sees it as a negative mitzvah prohibiting the use of G-d's name. The commentators struggle to explain the differences between these two great authorities and the subtle implications of swearing or not swearing in G-d's name.
