Thayer's Greek-English Lexicon is a revised and translated edition of C.G. Wilke's Clavis Novi Testamenti, which was first published in 1841. After numerous revisions by both Wilke and his successor, C.L. Wilibald Grimm, Joseph Henry Thayer took over the project. This current publication is a reprint of the revised and enlarged fourth edition of a work that for many years has been a standard in New Testament study. This justly famous opus is the one indispensable book for the study of the words of the Greek text of the New Testament, a life companion for every earnest minister of the Word of God.
