John Nelson Darby, The Gospels, Acts, Epistles, and Book of Revelation: Commonly called the New Testament. A New Translation from a Revised Text of the Greek Original. London: G. Morrish, 1867. Second edition 1872. Third edition 1884.

John Nelson Darby (1800-1882) was educated at Trinity College, Dublin, where he graduated in 1819 as Classical Medallist. He was ordained as a priest in the established church in Ireland in 1825, and ministered among country people in remote places. In 1827 he came to believe that the church to which he belonged was hopelessly corrupt; and, on the basis of his independent study of Scripture, he also came to believe that a Christian was obliged to separate himself from all corrupt organizations. So he resigned his position as a clergyman, and began to associate with certain ‘brethren’ in Dublin who shared his views. Because he was unmarried and had inherited a large estate, he had no need of a salary. In Dublin he met Benjamin Wills Newton, who recognized Darby’s gifts and invited him to minister among like-minded people in Plymouth, England. By the year 1832 a congregation was definitely formed there under Darby’s leadership. This was the beginning of the so-called ‘Plymouth Brethren’ movement, to which Darby would devote the rest of his life. In the year 1837 he went to the continent to promote his teachings among Methodists and Baptists there. By 1840 he had established several congregations in Switzerland and France. In 1853 he went on to Germany, where he established congregations in Dusseldorf, Elberfeld, and in other towns. He was dissatisfied with the existing Bible versions in French and German, and so he collaborated with German and French followers in the creation of new versions in those languages. With some German associates he produced the ‘Elberfelder Bible,’ 1 and with French-speaking followers he produced the ‘Pau Bible.’
Darby did not feel such a need for a new translation in English, because he considered the King James Version to be adequate for most purposes, and he encouraged his followers to continue to use it. But, he decided to produce a highly literal English version of the New Testament for study purposes. This New Testament was first issued in parts, beginning with the Gospel according to Matthew in 1865. The New Testament was completed in 1867. The version is exceedingly literal, based upon modern critical editions of the Greek text, and abundantly supplied with text-critical and philological annotations. The annotations are by far the most comprehensive and detailed to be found in an English version. It was consulted by the translators of the English Revised Version of 1881 (see F.F. Bruce, History of the Bible in English, 3rd ed., 1978, p. 132).
After Darby’s death in 1882, certain of his followers in England produced an English version of the Old Testament based upon Darby’s French and German translations. In 1890 this was published as the Old Testament portion of The Holy Scriptures. A New Translation from the Original Languages by J. N. Darby (G. Morrish, 1890). A later edition with abridged annotations (omitting the references to Hebrew and Greek manuscripts) was published by Stow Hill Bible and Tract Depot in 1939, and reprinted by Bible Truth Publishers in 1961. The Morrish edition of 1890 (with unabridged annotations) was reprinted by Bible Truth Publishers (Addison, Illinois) in 1983.
