The first aria is accompanied by the two oboes d'amore. The theme is related to the chorale melody, but turned to the major mode and in a swinging 12/8-time. The voice picks up the same theme and elaborates the word "gewandelt" (changed) in an extended coloratura. Musicologist Boyd notes a similarity to the aria Et in Spiritum sanctum from Bach's later Mass in B minor, both are for the bass, in a compound time, in A major and with two oboes.
