Lecha Dodi (part 2) and the 7 Haftarot of Comfort

(translation courtesy of DafYomi.co.il)

Our custom: We do not do so. Rather, the Maftir is in Yirmeyahu (2) "Shim'u Devar Hash-m", and on the Shabbos before Tish'ah b'Av, Chazon Yeshayah. This is because we conduct according to the Pesikta to say the three Haftoros of punishments (the Churban), i.e. "Divrei Yirmeyahu", Shim'u Devar Hash-m, and Chazon Yeshayah. Our custom: After Tish'ah b'Av we say seven of consolation and two of Teshuvah. They are Nachamu Nachamu, va'Tomer Tziyon, Aniyah So'arah alone, Anochi Anochi, Rani Akarah, Kumi Ori, Sos Asis, Dirshu and Shuvah. Explanation: The reason we read Aniyah So'arah before Rani Akarah (even though the latter precedes Aniyah So'arah in Yeshayah 54) is because it is normal for consolations to progress and improve. Summary: This order of Haftoros begins with Parshas Pinchas. The Siman of the Haftoros is DaShaCh (Divrei (Yirmeyah), Shim'u, Chazon), NO'A, ARaK, ShaDaSh. We always say Sos Asis in Parshas Netzavim, which is the Shabbos before Rosh Hashanah, since it is the end of the consolations. We say Dirshu [at Minchah] on Tzom Gedalyah and Shuvah on the Shabbos before Yom Kipur. When there is a Shabbos between Yom Kipur and Sukos, then we say Dirshu on the Shabbos before Yom Kipur, for it says in it "Dirshu Hash-m b'Himatz'o", which is during the [10] days of Teshuvah; We say Shuvah between Yom Kipur and Sukos, for it says "v'Nasan Lachem... Moreh u'Malkosh" and "va'Shem Nasan Kolo Lifnei Cheilo", which discuss water, so it is appropriate before Sukos. Support: This custom never changes, according to the Pesikta. Also R. Tam explained like this. Alternative opinion: This is unlike the Rav ha'Chovel, who reverses and mixes up the order to say that Shuvah is before Yom Kipur, and Sos Asis is between Yom Kipur and Sukos. This is wrong, for we do not interrupt between the six Haftoros of consolation and the seventh (Sos Asis). ...
