This monumental reference work, complete in ten volumes, is the authorized and unabridged translation of the famous Theologisches Wörterbuch zum Neuen Testament, known commonly as "Kittel" and considered by many scholars to be the best New Testament Dictionary ever compiled. Mediating between ordinary lexicography and the specific task of exposition, TDNT (published by Eerdmans) treats more than 2,300 theologically significant New Testament words, including the more important prepositions and numbers as well as many proper names from the Old Testament. Presenting the words in the order of the Greek alphabet, TDNT typically discusses the following for each word: its secular Greek background, its role in the Old Testament, its use in extrabiblical Jewish literature, and its varied uses in the New Testament. Substantial bibliographies and footnotes supplement the articles.
One of the most widely-used and well-respected theological dictionaries ever created, TDNT is indispensable for studies in the Greek New Testament and theology. Words were selected for inclusion in this dictionary based on their theological significance. The historical development and theological nuances of each word are exhaustively explored. The authors trace usage in classical Greek literature, the Old Testament (LXX) and extrabiblical texts, and New Testament passages.
As you can see, TDNT ("Big Kittel") is a massive reference work. The abridged 1,356-page version of TDNT is available as an unlock.
