 In Leipzig, Advent was a quiet time ("tempus clausum"), thus no cantata music was performed in services from Advent II to Advent IV.In order to use the music again, Bach had to dedicate it to a different liturgical event and chose the 26th Sunday after Trinity with a similar theme.The prescribed readings for this Sunday were from The Second Epistle of Peter, "look for new heavens and a new earth" (), and from the Gospel of Matthew, the Second Coming of Christ, also called Second Advent ().
