O help us, Lord; each hour of need. H. H. Milman. [Lent.] First published in Bishop Heber's posthumous Hymns, &c, 1827, p. 52, in 6 stanzas of 4 lines and appointed for second Sunday in Lent, being based on the Gospel of that day. In his Selection of Psalms & Hymns, 1837, Milman omitted stanzas iv. and v., thus reducing it to 4 stanzas of 4 lines and each stanza beginning with the words, "Oh! help us." In this form it has come into extensive use in all English-speaking countries. In the Mitre Hymn Book, 1836, No. 190, it is partly rewritten by E. Osier as, "O help us, Lord! in all our need." This is repeated in Osier's Church and King, June 1, 1837, but it has failed to attract attention. Another arrangement, beginning with stanza ii., "O help us, when our spirits bleed," is sometimes found in modern hymnals.
