This may be best demonstrated by examining the chapters Leviticus xvii.-xxvi.  At present they are incorporated in the Priestly Code, having undergone a revision with that view, which in some places adds little, in others a good deal.  Viewed, however, as they originally were, they form a work of a peculiar character by themselves, a work pervaded by a somewhat affected religious hortatory tone, which harmonises but little with the Priestly Code.  The author worked largely from earlier authorities, which explains, for example, how chapter xviii. and chapter xx. both find a place in his production.  Leviticus xvii.-xxvi is incomparably instructive for the knowledge it affords of literary relationships:  it is a perfect compendium of the literary history of the Pentateuch. 2

As with Deuteronomy, so with this legislation; it is clear that it goes back to the Jehovistic legislation of Sinai (Exodus xx.-xxiii.) as its source.  It also bears to have been given on Mount Sinai (xxv. 1, xxvi. 46).  It is addressed to the people, and is popular in its contents, which are chiefly of a civic and moral character.  It is meant only for the promised land and for settled life, not for the wilderness as well.  The festivals are three in number, and have not quite parted with their character as feasts of harvest.  Among the sacrifices the sin-offering and the trespass-offering are wanting.  The legislation does deal with the cultus to a disproportionate extent, but the directions about it do not go into technical details, and are always addressed to the people.  Even in those directions which concern the priests the people are addressed, and the priests are spoken of in the third person.  Nor are palpable points of contact wanting.  Leviticus xix. 2-8, 9-18, may be regarded as counterparts of the first and second tables of the decalogue.  The precept, “Thou shalt not respect the person of the poor, nor honour the person of the mighty,” xix. 15, is a development of that in Exodus xxiii. 3, and a number of other precepts in Leviticus xix. could stand with equal appropriateness in Exodus xxii. 17 seq.  The directions in Leviticus xxii. 27-29 are similar to those of Exodus xxii. 29, xxiii. 18, 19.  In the same way those of Leviticus xxiv. 15-22 are based both in contents and form on Exodus xxi. 12. 1
