 That's a stand-in for the entire Torah, for the entire revelation and covenant that was given to the Jewish people. A covenant that includes 613 laws, about which Garraway says ancient rabbis loved to argue. The one they really hone in on is Shabbat. So the commandment to keep the Shabbat versus the commandment to remember the Shabbat. And the different wording appears in Exodus and Deuteronomy.
