" It takes no great imagination to see that this picture of David is drastically different from the portrayals given in the Samuel traditions. It is not hard to see that such a constructed picture of David surely serves the context of the fifth century and no doubt serves the specific claims of the Levitic priesthood. The truth about David given here is that David is a pious, cultic man who finds his life shaped and enhanced by such explicit religious commitment. He is indeed a "man of the assembly. "
