Biblical scholar Dr. Alexander Rofé posits a Deuteronomic strata which "reflects the strength and demands of the Jerusalem priesthood" following upon the reforms of King Yoshiyahu in the mid- to late 7th century BCE. The third Deuteronomist (and the latest) is the most easily identified, since they are the Deuteronomist most interested in Priestly themes such as purity, proper sacrifice, and the priests. This third Deuteronomist seems to have confined his additions to the book of Deuteronomy (almost exclusively confining himself to hortatory and laws).
