Aish Tukad is a ḳinah for Tishah b’Av, usually recited towards the conclusion of the set of dirges for the morning service (in Goldshmidt’s numbering, it is number 32 of our 46 Kinot). According to Goldshmidt’s introduction, the structure of this Piyyut is based on a Midrash in Eicha Zuta 19, where Moses’ praises for God and Israel are seen as parallel to Jeremiah’s laments, thus creating the concept of a comparison between the joy of the Exodus and the pain of the Temple’s destruction.

“Yom Nilḥamu Vi” is the reshut offered before the Barkhu preceding the Shaḥarit blessings before the Shema. It is the eighth reshut among the reshuyot in the Old Sefaradi Tiqun for Shabbat Ḥazon — the final shabbat before 9 Av.

“Nishmat Emunim” is the third reshut offered before Nishmat at the outset of the Zemirot (preceding Shaḥarit). It is the fifth reshut among the reshuyot in the Old Sefaradi Tiqun for Shabbat Ḥazon — the final shabbat before 9 Av.
