Johann Sebastian Bach composed the church cantata (Who only lets dear God rule), 93 in Leipzig for the fifth Sunday after Trinity and first performed it on 9 July 1724. He based the chorale cantata on the hymn of the same title by Georg Neumark (1657). It is part of his chorale cantata cycle. History Bach composed the chorale cantata in 1724 as part of his second annual cycle for the Fifth Sunday after Trinity. Only continuo parts of the first four movements survived of the first performance. The manuscripts of the complete music date from another performance around 1732/1733, therefore it is unknown if the cantata had the same structure from the beginning. The prescribed readings for the Sunday were from the First Epistle of Peter, "Sanctify the Lord God in your hearts" (), and from the Gospel of Luke, Peter's great catch of fish (. The cantata text is based on the chorale in seven verses of Georg Neumark, written in 1641 and published in 1657 in . The chorale is connected in general to the prescribed readings. Specific reference to the Gospel appears in the recitative addition of movement 5. The words of the chorale remain unchanged in movements 1, 4 and 7 in a symmetric arrangement. The changes in the other movements are the work of an unknown poet. In movements 2 and 5 he kept the original words but expanded them by recitatives, in movements 3 and 6 he transformed the ideas of the chorale to arias. This chorale cantata is not to be confused with the chorale prelude of the same name, BWV 642. That chorale prelude, which is in the Orgelbüchlein collection, was also based upon the hymn by Georg Neumark. Scoring and structure The cantata in seven movements is scored for four soloists—soprano, alto, tenor and bass—a four-part choir, two oboes, two violins, viola, viola da gamba and basso continuo. Chorus: Recitative (+ chorale, bass): Aria (tenor): Duet aria (soprano, alto): Recitative (+ chorale, tenor): Aria (soprano): Chorale: Music In the central duet violins and violas play the melody of the chorale. Bach later arranged this movement for organ as one of the Schübler Chorales, BWV 647. The opening chorus is a concerto of three elements: the orchestra, dominated by the two oboes, playing an introduction and ritornellos, the cantus firmus in the soprano, and the other voices which start each of
