Bonei Olam Bolts of Hizzuk: R Shlomo Farhi - The First Mitzvah in the Torah

I can't ask you enough as a rabbi to do Torah mitzvot. I'll ask you to keep kosher and Shabbat and the holidays and saddaka and a lot of things, but maybe you won't do all the mitzvot I'll suggest. So, could you help me with the first one in the Torah, the Torah mitzvah of Peru or Vu, the most important mitzvah, the mitzvah of our future.
