I realize that the English translation of עשרת הדברים / דברותעשרת הדברים / דברות is better translated as "Ten pronouncements" rather than "10 Commandments". However, in viewing the text, 2 - 10 seem to be commanding some action (e.g. "Don't have any other gods; respect your parents, etc.)
The first one, "I am your G-d who took you out of Egypt..." doesn't seem to command anything. It seems more like a statement of fact or history.
Does anyone (Ramban, Rambam, etc.) count this as a mitzvah / "commandment"? If so, how do they consider this a commandment of there is no "verb" or directive to do anything as the other 9 have?
