Parshanut su Levitico 23:46

And you reap its harvest. Here, Hashem’s will is revealed that Bnei Yisroel should not become materialistic in working the land. The Creator gave many commandments relating to each activity in the field, in every step, to unite all of a human being’s activities to Hashem. All the materialistic activities become illuminating and radiant ways to reach true perfection and closeness with Hashem … And so, at the beginning of the harvest the Torah commands to bring the omer and the “two breads” to Hashem, and then they will be permitted to eat from the new crop. Similarly, at the end of the harvest you may not harvest completely, rather you must give to the poor, and in the middle of the harvest you must not gather the gleaning … The principle is that the beginning, middle, and end of the harvest is sanctified to Hashem, and sanctified to the matters by which mercy and kindness will be implanted within them. These are the very means by which a Jew reaches the fulfillment of completeness and the purpose acceptable to Hashem. Therefore, the section on appointed times concludes (v. 22), “When you reap the harvest …” Although these commandments were previously written in Parshas Kedoshim, it was repeated to arouse our hearts to this realization.
