פֿאַרבונדן אויף דברים 15:2

And just as Shevi'it remits the debt of a loan, so too does Shevi'it release an oath, as it is said (Deut. 15:2, Fox tr.), "This shall be the matter [of the release]" -- the "matter" that Shevi'it releases is that it releases oaths. And [as to] a matter that Shevi'it does not release, it [also] does not release an oath [concerning that matter]. Rabbi Shimon says, it does release it, and one does not inherit from that which has been released, as it is said (ibid.), "every creditor shall release the debt he claims from his fellow."

But on the seventh [year] you must let it rest, and abandon it [by not eating its produce], and let the needy among your people eat it. What they leave over, the beasts of the field can eat. Do the same with your vineyard and your olive [trees].
