 Although nominally the work of the above-named committee, Medhurst did the lion's share, and he did a final revision in 1836.He also took part in the translation of the Old Testament published by Gutzlaff in 1840.In addition to translating the Old Testament, Gutzlaff modified the version of the New Testament which he and Medhurst had prepared jointly; and he revised and printed some twelve editions of it.
