“Heil’ge Sabbath-Ruhe” is a hymn selected by Rabbi Gotthold Salomon, Immanuel Wohlwill, and Maimon Fraenkel for inclusion in the Hamburg Temple Hymnal (1833), hymn №342, p. 415. The first, fourth, and sixth stanzas were translated by Rabbi James Koppel Gutheim and published as “Der Sabbath (The Sabbath)” in his Hymns, for Divine Service in the Temple Emanu-El (1871) as hymn №1, pp. 2-3. The hymn also appears as the preface to Gotthold Salomon’s sermon “Der Segen des Sabbathtages” in Der berg des Herrn: Kanzel-vorträge über den Decalog (1846), p. 32 lending me to think that the hymn was at the very least appreciated by him, and possibly also written by him. –Aharon Varady . . .
