Despite the more or less direct reference to the 613 Mitzvos in the Torah, only a few of them are mentioned in the text explicitly to be observed in fact.
For example, Torah mentions Abraham circumcizing Itzhak and Ishmael or eating Matzah in the desert on the first Pesach or Boaz making [a sort of] Yibum.
Interestingly, I don't see the actual Mitzvos mentioned so often in Tanach.
Did anybody make a list of those? How many are there?
