THE SEVEN HAFTAROT OF COMFORT

Rabbi Avraham ben David of Luneil, the author of "Sefer HaManhig," writes:

"From Parshat Bereshit (Genesis) through the 17th of Tammuz (on the Jewish calendar) the Haftarah (readings from the prophets) is chosen to correspond to the Parshah topic by topic but from there on - the choice of Haftarah is determined entirely by the time of year and the corresponding historical events" (Hilchot Taanit, Din 16).
