In this week’s Torah portion, we read of two special mitzvot given to the Jewish people while we were still enslaved in Egypt. One is Rosh Chodesh, the mitzvah of blessing the new moon. The other is the establishment of the Jewish calendar, with the month of Nisan at the start of it. What is the significance of these mitzvot? Why were they given to the Jewish people before the rest of the Torah? And what are the lessons they teach us about the nature of our relationship with our Creator?
