As well as publishing writings on every aspect of Christian doctrine and practice, J.N.Darby also translated the Holy Scriptures into German, French and English, taking advantage of the great New Testament manuscripts that had come to light since the days of the Authorised Version, and the various critical editions that had been published.

Attributing the Bible translations to J N Darby alone is misleading because he worked with others in the German and French translations and the unfinished English Old Testament was completed by others after J N D’s death.
From Pau, in France, J N Darby wrote in 1879: “I am engaged in translating the Old Testament into French: we are towards the end, but it will have to be revised. It has been a laborious work, and it is not the way of reading scripture that nourishes; still it instructs, and makes one's knowledge of it accurate in detail.”
