Unser Mund sei voll Lachens in D major, BWV 110

Bach composed the cantata in his third year as Thomaskantor in Leipzig. He used a text by Georg Christian Lehms, which was published already in 1711. The text has no recitatives alternating with arias, but instead three biblical quotations, opening with verses from Psalm 26, then a verse from the Book of Jeremiah about God's greatness, and finally the angels' song from the Nativity according to the Gospel of Luke. The closing chorale is taken from Caspar Füger's "Wir Christenleut".
