Leviticus 25:22

עד השנה התשיעית UNTIL THE NINTH YEAR — i. e. until the Feast of Tabernacles of the ninth year which is the time when the crop of the eighth year comes ‎(בא תבואתה) into the house (the granaries). For during the whole summer-time (the fruits) remained in the fields inthe barns, and in Tishri was the time for gathering them into the house. Sometimes indeed it th)e soil) had to bring forth fruits for four years, viz., during the sixth year preceding the seventh “Shemittah” (i. e. in the forty-eighth year of the Jubilee-period) when they had to refrain from agricultural work two successive years, viz., the Sabbatical year and the Jubilee immediately following it. This verse, however, (which mentions only an increase sufficient for three years) is said (written) with reference to all other (i. e. ordinary) Sabbatical years.

And you shall sow the eighth year, and eat yet of old fruit until the ninth year; until her fruits come in, you shall eat of the old store.

וּזְרַעְתֶּ֗ם אֵ֚ת הַשָּׁנָ֣ה הַשְּׁמִינִ֔ת וַאֲכַלְתֶּ֖ם מִן־הַתְּבוּאָ֣ה יָשָׁ֑ן עַ֣ד ׀ הַשָּׁנָ֣ה הַתְּשִׁיעִ֗ת עַד־בּוֹא֙ תְּב֣וּאָתָ֔הּ תֹּאכְל֖וּ יָשָֽׁן׃
