In that service, his fourth in Leipzig, he performed it together with a new cantata , after he had started his tenure as cantor with cantatas in two parts, , and . He treated the same chorale in the chorale cantata , for the same occasion in 1724. Bach revived the cantata once more in 1746 or 1747. Bach structured the cantata in six movements, beginning with a duet, followed by a series of alternating recitatives and arias and concluded by a chorale. Similar to several other cantatas on words by Franck, it is scored for a small ensemble: four vocal soloists (soprano (S), alto (A), tenor (T) and bass (B)), oboe (Ob), two violins (Vl), viola (Va), and basso continuo (Bc) including bassoon (Fg). A choir is only needed for the chorale, if at all. The score, partly an autograph, is titled "Concerto. / Dominica post Trinit: / Brmhertziges Hertze der ewigen Liebe. ect. / â 5 Strom. 4 Voci / Tromba / 1 Hautb 2 Violini. 1 Viola. / Violoncello / è Fagotto. T. è Baßo con Cont. / di JSbach. / 1715", while "tromba" (trumpet) is struck in the cover of the set of parts. In Leipzig the oboe was replaced by a clarino (trumpet) for the instrumental cantus firmus of the chorale in the first movement. The duration is given as 16 minutes. In the following table of the movements, the scoring and keys are given for the version performed in Weimar in 1714. The keys and time signatures are taken from the Bach scholar Alfred Dürr, using the symbol for common time (4/4). The instruments are shown separately for winds and strings, while the continuo, playing throughout, is not shown. The opening movement is a duet of soprano and tenor, "" (Compassionate heart of eternal love). It is in two ways connected to the chorale which closes the work. The melody is played line by line as a by the oboe, embellished and in a dancing 6/4 time instead of 4/4.
