Speculation regarding liturgical occasion: Smend suggests that this setting served as the 7th movement of the Mark Passion (BWV 247) using the 4th verse of Ich, ich und meine Sünden. (See NBA III/2.1 KB, p.62 or III/2.2 KB, p.284)
Parallel fifths: Measure 5 contains consecutive fifths in contrary motion between the alto (E–A) and bass (A–D). In addition, two more instances of parallel perfect intervals occurs in the Dietel version of this chorale, which is considered a variant setting. (See below) In measure 5, Dietel has A–B quarters on beats 1–2 rather than C#–B, creating parallel octaves with the soprano. In measure 12, Dietel has C#–F# eighths rather than E–D#, creating parallel fifths with the soprano (C#–B).
