“Für den ersten Tag der Woche” was included by Yehoshua Heshil Miro in his anthology of teḥinot, בית יעקב (Beit Yaaqov) Allgemeines Gebetbuch für gebildete Frauen mosaischer Religion. It first appears in the 1829 edition, תחנות Teḥinot ein Gebetbuch für gebildete Frauenzimmer mosaischer Religion as teḥinah №5 on pp. 6-8. In the 1835 and 1842 editions, it also appears as teḥinah №5 on pp. 7-9. In a note to “Gebet am Tage der Gedächtnißfeier verstorbener Eltern, an deren Grabe zu sprechen” published in the 1835 edition, Miro records that Isaak Plessner sent this prayer to him, and from this we infer that its authorship may also be attributed to him. . . .
