Shabbat Nachamu
The Shabbat after Tisha B'Av is called Shabbat Nachamu ("Sabbath of Comforting"), after the Haftarah read on this day from the Book of Isaiah 40:1-26, which speaks of "comforting" the Jewish people for their suffering. This is the first of the seven Haftarahs of consolation that express the theme of redemption, leading up to the holiday of Rosh Hashanah, the Jewish New Year.
