'Now thank we all our God' is a popular Christian hymn. It is a translation from the German 'Nun danket alle Gott', written circa 1636 by Martin Rinkart (1586-1649), which in turn was inspired by Sirach, chapter 50 verses 22-24, from the praises of Simon the high priest. It was translated into English in the 19th Century by Catherine Winkworth. The tune for 'Now thank we all our God' is the 'Leuthen Chorale' and is attributed to Johann Crüger and written circa 1647, is used in J.S. Bach's BWV 386 and BWV 657. It is often used in Christian weddings and other joyous religious ceremonies, and in Germany it is sung on occasions of national thanksgiving.
