Singen wir aus Herzensgrund. [Grace after Meat.] Wackernagel, i., p. 776, cites this us No. 6 of Schöner geistlicher Lieder achte, printed at Erfurt, 1563; but at iv., p. 579, he prints the text from the Hundert Chrietenliche Hanssgesang, Nürnberg, 1560: and from J. Eichorn's Geistliche Lieder, Frankfurt a. O., 1569, in 6 stanzas of 7 lines. The broadsheet, Nürnberg, eds., which, in his Bibliographie, 1855, pp. 279, 308, he had dated 1556 and 1560, he afterwards said were of later date. Mützell. No. 559, prints it from a 1568 ed. of Eichorn's Gesang-Buch. It is found in Porst's Gesang-Buch, ed. 1855, No. 681. It has sometimes been erroneously ascribed to E. Alber, to B. Bingwaldt, or to N. Selnecker. Translated as:—
"Now give thanks ye old and young." By J. C. Jacobi, 1725, p. 6. Included in the Moravian Hymn Book, 1154, pt. i., No. 316; but only partly repeated in later eds., e.g. 1886, No. 1197, where only the stanza beginning, "Praise our God, it is but just," is from this hymn.
