This chapter critically examines the literary figure of Moses in Deuteronomy, particularly the book’s directive that Mosaic prophecy have an ongoing place in Israel (18:15–22). It begins by examining Moses as Deuteronomy’s distinctive persona, YHWH’s covenant mediator able to present a veritable divine voice to the reader. It then turns to Deuteronomy’s vision of leadership in an ideal Israel, including official prophetic leadership. Deuteronomy promises a Mosaic prophet for each new generation, a prophet who will stand among YHWH’s heavenly confidants and directly hear YWHW’s will for communication to Israel. It surveys the employment of the Mosaic paradigm in the Tetrateuch (Gen, Exod, Lev, Num), in the Former Prophets (Josh, Judg, 1-2 Sam, 1-2 Kgs) or Deuteronomistic History (Deut, Josh, Judg, 1-2 Sam, 1-2 Kgs), and in the Latter Prophets (Isa, Jer, Ezek, Hos, Joel, Amos, Obad, Jonah, Mic, Nah, Hab, Zeph, Hag, Zech, and Mal). Biblical figures of special interest include Deborah, Samuel, Elijah, Elisha, Hosea, Huldah, Jeremiah, and Malachi. Taken together, the evidence examined shows that the core elements of Mosaic prophecy predate Deuteronomy and are amply attested in the pre-exilic prophets, mostly in those prophets oriented on the Sinai covenant.
