The Lord gives Moshe precise instructions concerning what should constitute purity and sacredness for Aharon and the priests; also sheds light on the ritual purity of animals for sacrifice. Then, it informs about the moedim (festivals that happen at fixed times)—Shabbat, Pesach, Yom Kippur, Sukkot—regarding the date of celebration, form and duration, in addition to the punishment due in case of breaking the rules. There are norms about some objects of the Temple. We still read about penalties corresponding to some disruptive social behaviors.
I like to find the little messages within the parshiot, within each of the sections of our Torah. And they are always there. In each parashah there is a big story, a development of an idea in the middle of which, or at the end of which, suddenly sometimes, or more naturally at other times, a thought, a descent of line or lineament arises, that does not always have the weight of a mitzvah, but it does become a sort of maxim to follow. In general, with an ethical or moral content.
