So, just how and when did the notion of a Sabbath year beginning with Tishri, the seventh month, get considered and implemented by the Jewish religious leaders? Needless to say, with Part 2 we’re going to find out.
The Transition to the Tishri Year
The New Year date of Tishri 1 for the Sabbath year is an offshoot of late Talmudic interpretation. As has been previously noted in Part 1, Scriptures never claim that the seventh month began a regular Sabbath year.
The deduction that Tishri began a Jubilee year was itself a misreading of Leviticus 25:8-13. The rabbis of the post-Bar Kochba period, in an effort to “build a fence around the Law,”21 merely extended their misreading of Leviticus 25:8-13, which dealt only with the year of Jubilee, to the regular Sabbath year.
