"Speak"

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 haKippurim, 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.
