Because you’re interested in Deuteronomy and its composition and ideological function, you’ll be particularly excited to see the inimitable Carly Crouch’s Israel and the Assyrians: Deuteronomy, the Succession Treaty of Esarhaddon, & the Nature of Subversion. From the introduction:
A prominent feature of attempts to ground the deuteronomic text in a historical context over the last half century has been the observation of certain affinities between Deuteronomy and ancient Near Eastern vassal treaties and loyalty oaths. More specifically, it has been suggested that the book of Deuteronomy, in some more or less original form, constituted a subversive appropriation of Neo-Assyrian imperial ideology in favor of a Yahwistic theocentricity: a text deliberately designed to undermine the authority of the Assyrian king by planting YHWH in his stead. The prevalence of this assertion has its roots in the widespread recognition of similarities between elements of Deuteronomy, especially chapters 13 and 28, and Assyrian vassal treaties and loyalty oaths, with a particular focus on the Succession Treaty of Esarhaddon, commonly referred to as VTE. . . . The following aims to go beyond the doubt cast on the nature of Deuteronomy’s relationship with VTE to question the nature of its relationship with Assyrian ideology more widely and, as a consequence, to challenge the interpretation of the book in subversive terms.
