Speculation regarding liturgical occasion: Since this chorale appears in the Dietel Collection, there is a strong possibility it came from a cantata (or other choral work) that is now lost. Furthermore, we can speculate that the setting originated from a cantata for the 17th Sunday after Trinity, based on the setting’s position in the Dietel Collection and on the fact that BWV 47.5, the only other four–part setting of this tune from extant choral works, is from a cantata for Trinity +17.
Dietel 74 & 75 = from Trinity +11
Dietel 76 & 77 = from Trinity +12
Dietel 80 & 82 (& 83?) = from Trinity +13 (See notes for Dietel 83 (BWV 335))
Dietel 84 = from Trinity +14
Dietel 85 & 87 = from Feast of the Archangel Michael
Dietel 88 & 89 = from Trinity +16
Dietel 90? & 91 = Trinity +17
Dietel 92 = Trinity +18
Dietel 93 = Trinity +19
Dietel 94 = Trinity +21
