The agricultural aspects of the Chagim are often forgotten in today’s world of finance and commerce. People would plant their fields around Sukkos, cut the crops at Pesach, and leave them to dry until Shavuos when they would gather in the yield – hence the alternative name for Shavuos, Chag Ha’Asif – the Chag of Gathering. The main feature of Shavuos was the Omer offering, where people would bring the first two bushels they harvested to Jerusalem.
People nervously check their investments to see if they work out. It’s the same for crops, between planting and harvesting. Once cut, owners can be satisfied with the certainty of that year’s yield. Yet in Judaism, the freshly cut crops would be off-limits until people brought the Omer offering. This then permitted consumption of the rest. Shmitta and Yovel govern land use so that people relinquish control and effective ownership of their land every few years, and the Omer serves a similar purpose.
Typically, communal offerings consist of a single animal or unit representing the united Jewish people. Why is the Omer made up of two portions?
Rav Hirsch teaches how the laws regulating the use of the Land of Israel instill a sense of gratitude and trust in a person. That little bit of doubt, that little bit of insecurity, are exactly the points at which a person can actionably show their dependence and gratitude for the blessings they have.
When a communal offering has more than one unit, it is for the constituent parts of the Jewish people. There are two portions to the Omer offering to remind us that we cannot enjoy our blessings unless others can too. It’s part of the trust and thanks we owe for what we have.
We cannot say thank you for our blessings without sharing them as well.
