The Stylistic Argument
ÒBy its taste for barren names and numbers and technical descriptions, the Priestly Code [P] comes to stand on the same line with Chronicles and the other literature of Judaism which labors at an artificial revival of the old tradition.  Of a piece with this tendency is an indescribable pedantry, belonging to the very being of the author of the Priestly Code.  He has a very passion for classifying and drawing plans; if he has once dissected a genus into different species, we get all the species named to us one by one every time he has occasion to mention the genus.Ó – Wellhausen, Prolegomena, 350.
