(Awake, calls the voice to us), BWV 140', also known as Sleepers Wake, is a church cantata by Johann Sebastian Bach. He composed the chorale cantata in Leipzig for the 27th Sunday after Trinity and first performed it on 25 November 1731. It is based on the hymn "" (1599) by Philipp Nicolai. Movement 4 of the cantata is the base for the first of Bach's Schübler Chorales, BWV 645. The cantata is a late addition to Bach's cycle of chorale cantatas, featuring additional poetry for two duets of Jesus and the Soul which expand the theme of the hymn.
