Revelation, as the most fundamental theological element in the Abrahamic religions, establishes a connection between the unseen realm and the human world. This study, adopting an analytical–comparative approach grounded in religious semantics, examines the nature and language of revelation in the Holy Qur’an and the Old Testament. The main objective is to elucidate the essential similarities and differences in the conception of revelation. In the Qur’an, revelation is a divine, verbal, and descensional phenomenon that is transmitted swiftly and secretly (through inspiration, indication, or writing) to the heart of the Prophet, possessing a supernatural, infallible, and propositional nature. In contrast, in the Old Testament, revelation is the self-disclosure of the Divine within the context of history and human language, expressed through Hebrew verbs such as *galah* (to reveal), *ra’ah* (to see), and *yada‘* (to know), emphasizing its historical, relational, and theophanic dimensions.



The research methodology involves extracting key lexical items from the sacred texts, conducting linguistic and theological analyses, and performing comparative evaluations. The findings indicate that Qur’anic revelation centers on theological and descensional discourse, whereas Old Testament revelation emphasizes historical and phenomenological theology. These differences significantly shape the epistemological, legal, and cultural systems of the two traditions. The study fills a gap in previous scholarship by focusing on the linguistic and semantic aspects of revelation, offering a comprehensive understanding of revelation as a linguistic–ontological code.
