The Theological Wordbook of the Old Testament — what it is, and how BiblicalTools.org uses its reference numbers.
TWOT (Theological Wordbook of the Old Testament) is the definitive Hebrew lexicon for conservative evangelical scholars. Edited by R. Laird Harris, Gleason L. Archer Jr., and Bruce K. Waltke, it provides in-depth theological analysis of every significant Hebrew word in the Old Testament.
Unlike simple concordances, TWOT explores the theological significance of each word — how it develops throughout Scripture, its semantic range, and its role in biblical theology. First published in 1980, it remains the gold standard for Hebrew word studies.
BiblicalTools.org uses the TWOT numbering in its Bible Reader and lexicon: tap a Hebrew word and you see its TWOT reference number, the words that share its root, and the range of meaning from Brown-Driver-Briggs (1906) and Strong’s Hebrew Dictionary (1890), both in the public domain, via the Open Scriptures Hebrew Bible Project (CC BY 4.0). TWOT numbers are shown for reference only; the TWOT articles are not reproduced here, so take the number to the Wordbook itself for the full article.
TWOT doesn't just define Hebrew words — it explains their theological significance. Understand how words like hesed (lovingkindness), shalom (peace), and halak (walk) carry rich theological meaning throughout Scripture.
Each entry explores the full semantic range of the Hebrew word — its various meanings, nuances, and how context shapes interpretation. See how a single Hebrew word can carry multiple layers of meaning.
TWOT provides extensive cross-references showing how each word is used throughout the Old Testament. Trace theological themes from Genesis to Malachi with scholarly precision.
Written by respected conservative Hebrew scholars, TWOT maintains academic excellence while staying true to the authority and inspiration of Scripture. Seminary-level resources for everyday believers.
