The closing chorale is "Ertöt uns durch dein Güte" ("Kill us through your goodness" or "Us mortify through kindness"), the fifth stanza of Elisabeth Cruciger's "Herr Christ, der einig Gotts Sohn". Its melody is based on one from Wolflein Lochamer's Lochamer-Liederbuch, printed in Nürnberg around 1455. It first appears as a sacred tune in Johann Walter's Wittenberg hymnal Eyn geystlich Gesangk Buchleyn (1524).The usual four-part setting of the voices is brightened by continuous runs of the oboe and violin I. Isoyama thinks that Bach may have intentionally imitated the style of his predecessor Johann Kuhnau in the "elegantly flowing obbligato for oboe and first violin".John Eliot Gardiner describes the movement's bass line as a "walking bass as a symbol of the disciples' journey to fulfilment.
