This chapter reviews major trends and trajectories within previous research on metaphors in Isaiah, including rhetorical, structuralist, redaction-critical, ideological, and feminist approaches. In addition, it surveys recurring types of imagery that inform this prophetic book’s perspective on the relationship between Yhwh and his people. Various images of empires are discussed as examples of propagandistic rhetoric. Some metaphors are analyzed in more detail. It is thus demonstrated that the conceptual metaphor “people are plants,” with its emphasis on the transience of human existence, pervades the book of Isaiah. Among metaphors used about Yhwh, special attention is paid to “God is a parent.” The concluding section discusses the various feminine roles ascribed to personified Zion in several passages in chapters 40–66: daughter, wife, and mother.
