Trinitatis XXI is the 21st Sunday after Trinitatis, and we have no less than 4 Leipzig cantatas for this day. The first three (BWV 109, BWV 38, BWV98) are from the first three annual cantata cycles.

The second cantata, Aus tiefer Not schrei ich zu dir, BWV 38, is from the chorale cantata cycle, and is based on a penitential hymn by Martin Luther with the same name.

The fourth one, Ich habe meine Zuversicht, BWV 188, is from somewhat later and what we now have is a careful reconstruction because the original autographed score was cut up in pieces and sold to private individuals somewhere in the nineteenth century.

This cantata is also one of only ten cantatas we know of from a complete cycle of cantata libretti written by Christian Friedrich Henrici (1700-1764), writing under the pen name Picander. In the prologue of that bundle he writes that these texts will be put to music by the "incomparable Kapelmeister", meaning Bach. This means that there might have been a fourth complete cantata cycle, of which around 50 of 60 possible cantatas would be lost.
