In the first movement the words of Jesus are given to the
bass, the voice type which by convention was the (voice of Christ). A year earlier (in
Sie werden euch in den Bann tun, BWV 44), Bach rendered the announcement of Jesus in a two-part movement, a duet for bass and tenor followed by an agitated chorus. In this cantata, he set it as a recitative of only five measures. The instrumentation is novel, having long chords of the four oboes, two oboes da caccia and two oboes d'amore, accompany the voice above a
pedal point held by the continuo which creates a "sepulchral" sound, according to Julian Mincham. The Bach scholar
Christoph Wolff notes that this "opulent oboe scoring" with all four oboes playing together is used only in the two recitatives (1 and 3). The second movement, the first aria, is the longest of the work. It is sung by the tenor with an
obbligato part for violoncello piccolo, an instrument with a tenor-bass range. The "dark and shaded" timbre of the movement has been seen as representing the protection provided by Christ. Denying the fear of the threatening death, the violoncello piccolo plays continuous runs. Movement 3 is again a
recitativo accompagnato, even more complex than the first one; the strings play long chords, whereas all the oboes repeat the same four-note
motif throughout the movement, sung by the alto on the words "Ich bin bereit" (I am ready). The second aria is accompanied by the strings and the two oboes da caccia in
unison as obbligato instruments, thus both arias are dominated by instruments with a relatively low range (oboes de caccia having a pitch below that of a normal oboe). The opening line is appears three times, set similarly but not identically, which can be interpreted as a symbol of the
Trinity. The cantata is closed by a four-part chorale on the tune of "" by
Johann Crüger. == Publication ==
