Isaías 54:11 Halajá: Abudarham, Kitzur Shulchan Arukh & Shulchan Arukh, Orach Chayim

R'eh Anokhi: 'Uri 'Uri, Isaiah 51:9–52:10.^noteOr alternatively, 52:1–10. Both verses start with the same two words, but 51:9 is cited below. Some printings add here: "Some conclude with Isaiah 54:11–55:5." This is the practice in nearly every community today

And the Midrash punningly says that they established to say at the beginning of the prophetic readings of consolation "Comfort, comfort my people" (Isaiah 40:1) — that is to say, the Holy Blessed One said to the prophets, "Comfort, comfort my people!" Upon this the congregation of Israel responds, "But Zion says, 'the LORD has abandoned me!'" (Isaiah 49:14) that is to say, "I cannot be reconciled to the comfort of the prophets." And it says "Rise, rise, dress in strength, arm of the LORD; rise as days of old!" (Isaiah 51:9). And in places where it they conclude in place of this prophetic reading "Unhappy, storm-tossed" (Isaiah 54:11), it is as if to say the prophets respond and say before the Holy Blessed One, "Lo, the congregation of Israel is not reconciled to our comforting!" Upon this the Holy Blessed One responds and says, "I, I myself will comfort you" (Isaiah 51:12), and what's more, "Rejoice, barren one without children" (Isaiah 54:1), and what's more, "Rise, shine, for your light has come!" (Isaiah 60:1). To this, the congregation of Israel responds, "I will rejoice, rejoicing in the LORD" (Isaiah 61:10), that is to say, now I have something to rejoice and celebrate! "My soul will cheer in my God, who clad me in clothing of salvation" etc.

Beginning with the Shabbos following Tishah beAv and after that, for the next seven Shabbosos we read the haftoras "sheva denechamasa" [seven haftoras of consolation]. If the first day of Rosh Chodesh Elul occurs on Shabbos, the haftorah, Aniyah so'arah, is set aside ["O you afflicted, floundering in the storm,"] (Isaiah 54:11) and we read instead, "Hashamayim kis'i," [The heaven is My throne] (Isaiah 66:1), because this haftorah also contains consolation for Jerusalem. On the Shabbos of Parshas Ki Seitzei, when the haftorah Roni akarah [Sing, O barren woman] (Isaiah 54:1) is read, we conclude the haftorah with Aniyah so'arah, which is next to it. If, by mistake, on Shabbos Rosh Chodesh Elul, you said Aniyah so'arah, and you became aware of it before saying the concluding berachos, you should also say Hashamayim kis'i, and then say the concluding berachah. If you only became aware [of your error] after saying the concluding berachos, then you should recite, Hashamayim kis'i without the berachos. If Rosh Chodesh Elul occurs on Sunday, the haftorah, Machar Chodesh is set aside, [Tomorrow is Rosh Chodesh] (I Samuel 20:18), because it contains no consolation for Jerusalem, and the haftorah Aniyah so'arah is read.
