This chorale survives without text. The text that appears here is the one provided by editors of the Bach Gesellschaft Ausgabe (BGA).
Speculation regarding liturgical occasion: This chorale may have come from the Picander–Jahrgang cantata Wohin mein Herz for the 3rd Sunday after Trinity (Picander 44) with the 9th verse of Meinen Jesum lass ich nicht. (See NBA III/2.2 KB, p.225.)
