Ever wished you could search the Hebrew Bible or Greek New Testament by morphological features — without buying expensive software? Parabible is a free, open-source, browser-based tool that lets you read and search the original languages of Scripture with remarkable sophistication.^1 Built on morphologically parsed and tagged texts, it displays the BHS (Hebrew), Rahlfs LXX (Greek Septuagint), SBL Greek NT, and NET English translation side by side — no installation required.^2
Click any word in the original language and Parabible reveals its part of speech, tense, person, number, gender, and semantic domain. From there, you can build multi-term searches across phrases, clauses, sentences, or entire verses — filtering by specific books to narrow your results.^2 Under the hood, the search engine uses Clickhouse (an OLAP database) with a custom Rust-based function for blazing-fast queries across the full biblical corpus.^3 A next-generation server rewrite in TypeScript/Deno is in active development, with a modular data pipeline that supports adding new text modules.^4
Parabible was created by James Cuénod, a South African-born Old Testament scholar who holds a PhD in Biblical Theology from Wheaton College and now serves as Senior AI Translation Technologist at Seed Company, where he consults on AI tools for Bible translation projects worldwide.^3 He originally built the tool to help with his own exegetical research during a class with John Walton on the Book of Job, and the entire codebase is open source on GitHub with 11 repositories.^6 The tool has daily active users and continues to receive data pipeline updates.^3
