Aliya Summary: This Aliya begins a lengthy discussion about the Jewish holidays. After making brief mention of the Shabbat, the Torah talks about the holiday of Passover and the mitzvah of eating matzah. On the second day of this holiday, an “omer” barley offering is brought in the Temple. This is followed by a seven-week counting period that culminates with the holiday of Shavuot. After discussing the Shavuot Temple service, the Torah briefly interrupts the holiday discussion to mention the obligation, when harvesting fields, to leave certain gifts for the poor.
The Rambam and the Chinuch consider the counting of the Omer to be an independent mitzva which applies today.
