This exceptional cantata was probably first heard at the Thomaskirche in Leipzig on June 16, 1726, though scholars cannot rule out it being composed for a festival later that year or early in 1727. The new digitally-enhanced vocal score presented here is reproduced from the series first issued to coincide with the monumental Bach Gesellschaft Ausgabe by Breitkopf und Hartel of Leipzig just over a century ago with keyboard reductions by Bernhard Todt.
