This study presents a linguistic, semantic, historical, and philological analysis of the expression Hemdat Kol HaGoyim in Haggai 2:7. The research examines the phrase through multiple interpretive and textual dimensions, including Hebrew semantics, prophetic context, reception history, comparative Abrahamic interpretation, and the instability of meaning across religious traditions. The study argues that the expression functions as a layered semantic structure whose interpretation developed through successive theological and historical readings.
