His best known work is the
Bible concordance named after him, ''Strong's Exhaustive Concordance of the Bible
, first published in 1890, of which new editions are still in print. Numerous revisions, such as The Strongest Strong's Exhaustive Concordance of the Bible
and The New Strong's Exhaustive Concordance of the Bible'', along with adaptations of the concordance to translations other than the
Authorized King James Version while retaining the "Strong's" or similar branding, such as the
Strongest NIV Exhaustive Concordance are also available. "Strong's numbering" of Greek and Hebrew words, have dominated the enumeration of such words in Bible study helps to the present day, only recently being supplemented by Goodrick–Kohlenberger numbering. For the concordance, Strong numbered every
Hebrew or
Greek root word which was found, for ease of reference. This numbering system (8674 Hebrew roots and 5523 Greek roots) is now widely used in the
English-speaking world and also widely available on the web, where it can be used with many translations, often in conjunction with other
hermeneutic tools. In spite of the Greek roots being numbered up to 5624, there are 5523 actual entries, since 101 numbers were jumped over. At the end of the "Greek Dictionary of the New Testament" section of the first edition of ''Strong's Concordance'' is the following Note: "Owing to changes in the enumeration while in progress, there were no words left for Nos. 2717 and 3203–3302, which were therefore silently dropped from the vocabulary and references as redundant. This will occasion no practical mistake or inconvenience." Further, note that modern
Old Testament lexical systems often separate entries on
Aramaic words from those on Hebrew words, a practice initiated by
A Hebrew and English Lexicon of the Old Testament (an English work based on
Gesenius' Hebrew Grammar in German), which is commonly called "
Brown–Driver–Briggs" or "BDB" after its three primary authors. ==Other works==
