 The first stanza appears in the new first movement, the second is a cantus firmus in the second movement (the first movement of the Weimar cantata), and the other two may have been used in the fifth and eighth movements; both of these were chorale settings, as in the later Leipzig version.Wolff writes that Bach thus "may have anticipated the composition of the later series of chorale cantatas".It is not known when Bach composed the elaborate opening movement of the final version.
