The Hebrew scrolls newly discovered near Qumran at the north-western shore of the Dead Sea, which are attracting more and more the attention of New Testament students, are also very important for the evolution of Jewish Gnosticism. One may think especially of the fact that in some of these manuscripts the Hebrew word for ‘knowledge’ and related terms occur with a striking frequency, and that the dualistic cosmology of the new texts seems to be rather like certain fundamental ideas of Gnosticism. Since the archaeological evidence now proves that the Qumran manuscripts are pre-Christian, or were at least written in the first Christian century, one may very well state that new light can now be thrown upon the much debated question of a pre-Christian, Jewish Gnosticism.
