wrote for his application for the post of Cantor of St. Thomas Church, Leipzig and Directoris Chori musici of Leipzig, the cantata Du wahrer Gott und Davids Sohn, BWV 23. For this work (BC A 47b, Bach transposed it to F-sharp minor. The work was revived again (with the same setting and key) on 20 February 1724 (Quinquagesima or Estomihi Sunday), this time with brass instruments (Cornetto, Trombone I-III, all colla voce Cornet with Soprano, Trombone I with Alto, Trombone II with Tenor, and Trombone III with Bass (voice type)). In 1725, Bach revived (possibly a last-minute decision) his St John Passion. It is possible that he had in mind a revival of the Weimarer Passion, but realized that it was impossible, especially since the Leipzig liturgy required a Passion setting in two parts framing the sermon. However, this did not stop Bach from reusing material from the Weimar work in this new Passion setting. Of the nine movements mentioned in the above list, Bach would use five of them in the second version of the St John Passion: Chorale fantasia "O Mensch, bewein dein Sünde groß" E major (Coro: S A T B, Flauto traverso I/II, Oboe I/II, Violino I/II, Viola, Continuo), replacing the 1724 original Movement I ("Herr, unser Herrscher", G minor, Coro: S A T B, Oboe I/II, Violino I/II, Viola, Continuo). Movements 2-11 of 1724 work = Movements 2-11 of 1725 work. Aria with Chorale "Himmel reiße, Welt erbebe" F minor (Solo: B, Coro: S, Flauto traverso I/II, Continuo)--New Movement 12. Movement 12 of 1724 work = Movement 13 of 1725 work. Movement 13 of 1724 work = replaced by movement below. Aria "Zerschmettert mich, ihr Felsen und ihr Hügel" A major (Solo: T, Violino I/II, Viola, Continuo)--New Movement 14 (replacing Movement 13 of 1724 work). Movements 14-19 of 1724 work = Movements 15-20 of 1725 work (Movement 20 of 1724 work left out, Movement 19 of 1724 work replaced by new aria [see below]) Aria "Ach windet euch nicht so, geplagte Seelen" C minor (Solo: T, Oboe I/II, Continuo)--New Movement 20 (replacing Movement 19 of 1724 work). Movements 21-40 of 1724 work = Movements 21- 40 of 1725 work, Movement 40 replaced by new Chorale (see below) Chorale fantasia "Christe, du Lamm Gottes" G minor (Coro: S A T B, Flauto traverso I/II, Oboe I/II, Violino I/II, Viola, Continuo) On 17 November 1726, Bach composed
