Earth, rejoice, the Lord is King. C. Wesley. [Confidence in God.] Appeared in Hymns & Sacred Poems, 1740, p. 115, in 14 stanzas of 4 lines, and headed “To be sung in a Tumult." (Poetical Works, 1868-72, vol. i. p. 296.) In the Supplement to the Wesleyan Hymn Book, 1830, 6 stanzas were given as "Earth, rejoice; our Lord is King," and this arrangement is repeated in the revised edition of 1875. In some of the American hymn-books the original reading is retained.
