This book investigates the methodological fallacies inherent in the study of biblical language, specifically challenging the assumption that the etymology of a word determines its meaning in a given context. James Barr, a prominent biblical scholar, utilizes rigorous linguistic analysis to critique the common practice of deriving theological significance from the historical roots of Hebrew and Greek terms. He argues that meaning is primarily determined by usage within a specific linguistic environment rather than by the history of the word itself.

Experts widely recognize this work as a foundational text that fundamentally altered the landscape of biblical scholarship and exegesis. Readers frequently note the academic density of the prose, which requires a strong background in linguistics or theology to fully grasp the author's arguments.
