Tue Rechnung! Donnerwort, BWV 168

The text, which Franck had published in 1715, uses the prescribed reading from the Gospel of Luke, the parable of the Unjust Steward, as a starting point for thoughts about the debt of sin and its "payment", using monetary terms.

Bach structured the cantata in six movements and scored it intimately, as he did for many of Franck's works, for four vocal parts, combined only in the chorale, two oboes d'amore, strings and basso continuo.

Donnerwort in 1715 as part of the collection Evangelisches Andachts-Opffer, and Bach would probably have used at the time had it not been for a period of mourning for Prince Johann Ernst of Saxe-Weimar.

The cantata is concluded by the eighth stanza of Bartholomäus Ringwaldt's hymn "Herr Jesu Christ, du höchstes Gut" (1588).

The instrumental parts are for two oboes d'amore (Oa), two violins (Vl), viola (Va) and basso continuo (Bc).

[1] Christoph Wolff notes: Bach translates Franck's baroque poetry into an extraordinarily gripping musical form.

The virtuoso string writing in the opening aria prepares and then underscores the emphatically articulated "word of thunder, that can shatter even the rocks"[1] ("Donnerwort, das die Felsen selbst zerspaltet"), and which causes the blood to "run cold" ("Blut erkaltet").

[2] The oboes first play long chords, but finally illustrate the text figuratively, speaking of toppling mountains and "the flash of His countenance".

The musicologist Julian Mincham notes that Bach's recitative is "both melodic and dramatic throughout", showing his familiarity with "the best contemporary operatic styles".

"[9] The closing chorale, "Stärk mich mit deinem Freudengeist" (Strengthen me with Your joyful Spirit),[1][10] is a four-part setting.
