Moses said [to Pharoah], “You will even provide us with feast offerings and ascent-offerings so that we may offer them up to G-d, our G d.”
Exodus 10:25
Allegorically, Moses was saying that the Jewish people’s own spiritual resources are not sufficient; in order to serve G-d fully, we must sometimes also make use of resources provided by the world at large.
This includes not only physical resources but the lessons of history. It is for this reason that the Torah, before listing the commandments that G-d requires us to obey, describes the creation of the world and the events that led to the Giving of the Torah at Mount Sinai. This is because there are lessons in proper conduct and in our relationship with G-d that we need to learn from observing nature and human history.
As the Baal Shem Tov put it, a lesson in how to fulfill our Divine mission can be learned from everything that Divine providence arranges for us to see.
