In this aliyah, Hashem speaks to Moshe Rabbeinu to teach Bnei Yisrael the mitzvos that will apply once they enter Eretz Yisrael and begin to harvest the land. The Torah introduces the mitzvah of bringing the Omer, the very first sheaf of the barley harvest, to the Kohen to be elevated before Hashem.
The aliyah details the specific avodah of the Omer offering, which the Kohen elevates on the day after the first day of Pesach. Along with the sheaf of barley, Bnei Yisrael are commanded to bring a lamb as an olah, a minchah of choice flour mixed with oil, and a wine libation. Finally, the Torah establishes the strict prohibition of chodosh, forbidding anyone from eating bread, parched grain, or fresh ears from the new crop until the day the Omer offering is brought, a halachah that remains a law for all generations.
The Torah is telling us that when we enter the land and reap its harvest, before we take even a single bite of the new crop, we must bring the Omer offering to the Kohen. The very first yield of our hard work, the "reishis katzirchem," belongs to Hashem. Lichoira, a person works the field for months, sweating and worrying about the rain, and finally the grain is ripe. The natural human reaction is to immediately sit down and enjoy the fruits of his labor. But the Torah comes and sets a boundary: "V'lechem v'kali v'charmel lo sochlu", you cannot touch it until you bring the Korban to Hashem.
This is a tremendous yesod in our daily avodah. The yetzer hara wants us to believe that our success, our parnassah, and our achievements are entirely the result of our own strength and cleverness. By forcing us to stop and give the very first portion to Hashem, the Torah is training us to realize that everything we have is a gift from Him. Before we satisfy our own desires, we must first acknowledge the One Who gave us the ability to produce the harvest in the first place. Mimeila, this changes our entire relationship with gashmius; it elevates our physical enjoyment into an act of kedushah.
We must bring this emunah into our own daily lives. When you close a business deal, receive your paycheck, or experience a great success, do not immediately rush to spend it or pat yourself on the back. Stop for a moment. Dedicate the very first part of that success to Hashem, whether by writing a check for tzedakah, sitting down to learn a blatt Gemara as a thank-you, or simply saying a heartfelt Mizmor L'Sodah.
Today, before you enjoy any new success, profit, or good news, stop and dedicate the very first moment of that joy to Hashem by giving tzedakah or saying a perek of Tehillim to thank Him.
