"And the seventh year you shall leave it" — the Torah commands that the land be left fallow during the shemitah year. But the Mekhilta anticipates a well-intentioned objection. Someone might say: "Why did the Torah institute this? Surely it is so that the poor shall eat the produce that grows on its own. I will gather it in and distribute it to the poor myself — more efficiently, more fairly."
The Torah rejects this reasoning: "You shall leave it." The landowner must physically abandon the produce. He may not gather, organize, or distribute it, no matter how charitable his intentions. The poor come and take what they find on their own.
The Mekhilta explains that this means the owner must even allow breaches in the fences around his field. The field must be genuinely accessible to the public, not merely declared open while remaining physically enclosed.
However, the sages permitted repairs to fences "for the general good" — meaning basic structural maintenance was allowed to prevent the field from becoming a complete ruin.
This ruling reveals a deep principle about the shemitah. It is not merely a charitable program that happens to use agricultural produce. It is a statement about ownership itself. During the seventh year, the land does not belong to you. You cannot control access to it, organize its distribution, or play the role of benefactor. You must step aside entirely. The poor take directly from God's earth, without any human intermediary managing the process.
