Speculation regarding liturgical occasion: Häfner suggests that this setting may have come from the 50th cantata (Ach Gott, ich bin von dir) from the Picander–Jahrgang for the 7th Sunday after Trinity, using the 10th verse of Warum betrübst du dich, mein Herz. Alternatively, Klaus Hofmann has speculated that the setting may have originated from the lost funeral cantata for Ponickau Liebster Gott, vergißt du mich (Anh. 209) performed on 2 February 1727.
