"And this is the word of the shemitah": From here it was ruled: Shemitah releases a loan, but the Jubilee year (Yovel) does not release a loan.
For it would follow: If shemitah, which does not release servants, releases a loan, then Yovel, which releases servants, how much more so should it release a loan! It is, therefore, written "And this is the word of the shemitah" — shemitah releases a loan, but Yovel does not release a loan.
A kal vachomer (a fortiori argument) that shemitah should release servants, viz.: If Yovel, which does not release a loan, releases servants, then shemitah, which releases a loan, how much more so should it release servants! It is, therefore, written (Vayikra 25:13) "In this year of Yovel, each of you shall return to his holding: "This" (i.e., Yovel) releases servants, but shemitah does not release servants. Shemitah releases (loans), but Yovel does not release (loans).
