Praise to God, who reigns above. R. M. Benson. [St. Michael and All Angels.] Contributed to Hymns Ancient & Modern and after curtailment and alterations, was published therein in 1861. In the revised edition, 1875, the original text (still abbreviated) was restored, with the exception of two minor changes. These facts account for the two texts in Hymns Ancient & Modern of 1861 and 1875. The line in st, vi., "Thrilling through those Orders nine" refers to the (1) Seraphim; (2) Cherubim; (3) Thrones; (4) Dominions; (5) Princes;(6) Powers; (7) Might; (8) Archangel; and (9) Angel hosts, named in st. ii. and iii. In the American Church Pastorals, Boston, 1864, st. ii., iv., vii. of the 1861 text are given as:—"Seraphim His praises sing."
