“Nun jauchzt dem Herren, alle Welt” (Now rejoice to the Lord, all the world) is a German Christian hymn, a paraphrase of Psalm 100. The text was written by David Denicke, based on a metered paraphrase of the psalm from the Becker Psalter, and published in his 1646 hymnal. The song appears in modern German-language hymnals, such as the Protestant Evangelisches Gesangbuch and the Catholic Gotteslob. With a joyful melody derived from a 14th-century model, it is one of the most popular psalm songs in German.

Wikipedia says only that it’s from a Christmas carol:
The melody assigned to Denicke’s hymn, in triple metre, first appeared in the 14th century Moosburg Cantionale. It was originally used for a Christmas carol. The melody appears in the 1646 hymnal as one of eleven melodies in the appendix.
