Father of all, my soul defend. J. Merrick. [Psalms xvi.] First published in his Psalms Translated and Paraphrased in English Verse, 1765, p. 27, and again in W. D. Tattersall's rearranged edition of the same, 1797. In the 8th edition of his Selection 1819, No. 16, Cotterill gave a cento from this version (stanzas i., viii.-xi.) beginning, "God of our life, our souls defend." This was repeated in later collections. In The Calcutta Hymn Book, 1862, No. 16, this cento is repeated with the omission of stanza ii., and the alteration of the opening line to "God of my life, my soul defend." Another cento is given in Psalms & Hymns Selected for Public Worship, &c, Bedford, 1859-64. It is composed of Cotterill’s first stanza as above, and three stanzas from I. Watts's version of Psalms xvii., in his Psalms of David, &c, 1719, "Lord, I am Thine; but Thou wilt prove."
