It is common to take the law of Num. v 5-8 as being basically a repetition of the law of Lev. v 20-26 with one innovation. The author rejects this commonly held view, and argues that the two laws stem from different priestly schools and represent opposite conceptions with regard to to the relationship of cult and morality. Lev. v originated in the Priestly Torah (P) and reflects the sharp distinction made by this school between cult and morality. Num. v stems from the Holiness School (H) and reflects the ideology of this later priestly school that combines morality and cult by broadening the concept of holiness. The new ideology is best expressed in Lev. xix and it is reflected in the contents and terminology of the law of Num. v 5-8.
