Dem Gerechten muss das Licht in D major, BWV 195

Dem Gerechten muß das Licht (The light shall [ever rise again] for the righteous), BWV 195, is a church cantata by Johann Sebastian Bach for a wedding. He composed it in Leipzig, possibly in 1727, but only the incomplete scores of later performances from the 1740s survived. It uses two verses from Psalm 97 for the opening movement, and the first stanza auf Paul Gerhardt's hymn "Nun danket all und bringet Ehr" for the closing chorale. The librettist of the other movements is unknown.
