Leviticus 25:7

and for thy cattle, and for the beast that are in thy land shall all the increase thereof be meat, be used as food. The Sabbatical Pear was a civil year, which began after the harvest, in the late fall, for in the next fall, at the beginning of the eighth year, the cultivation of the land was resumed. God wanted to signify to the people of His covenant that He was well able to keep them, even without the labor of their hands, if they would strive to keep His covenant and he satisfied with His mercy.
