 The majority of scholars today continue to recognise Deuteronomy as a source, with its origin in the law-code produced at the court of Josiah as described by De Wette, subsequently given a frame during the exile (the speeches and descriptions at the front and back of the code) to identify it as the words of Moses.Most scholars also agree that some form of Priestly source existed, although its extent, especially its end-point, is uncertain.The remainder is called collectively non-Priestly, a grouping which includes both pre-Priestly and post-Priestly material.
