In this commentary, Hyun Chul Paul Kim brings together innovative interpretive approaches and the proposals of various scholars to interpret the book of Isaiah in light of the ancient literature/culture, intertextual allusions/correlations, and socio-historical contexts of the empires. While closely exegeting key issues of each chapter, the commentary also explores interpretive relevance and significance between ancient texts and the modern world. Engaging with theological messages of the book of Isaiah as a unified whole, the commentary will both illuminate and inspire readers to wrestle with its theological implications for today’s church and society.
