The Exhaustive Concordance of the Bible, generally known as Strong's Concordance, is a Bible concordance, an index of every word in the King James Version (KJV), constructed under the direction of James Strong. Strong first published his Concordance in 1890, while professor of exegetical theology at Drew Theological Seminary. Purpose The purpose of Strong's Concordance is not to provide content or commentary about the Bible, but to provide an index to the Bible. This allows the reader to find words where they appear in the Bible. This index allows a student of the Bible to re-find a phrase or passage previously studied. It also lets the reader directly compare how the same word may be used elsewhere in the Bible. Strong's numbers Each original-language word is given an entry number in the dictionary of those original language words listed in the back of the concordance. These have become known as the "Strong's numbers". The main concordance lists each word that appears in the KJV Bible in alphabetical order with each verse in which it appears listed in order of its appearance in the Bible, with a snippet of the surrounding text (including the word in italics). Appearing to the right of the scripture reference is the Strong's number. This allows the user of the concordance to look up the meaning of the original language word in the associated dictionary in the back, thereby showing how the original language word was translated into the English word in the KJV Bible. Strong's Concordance includes: The 8,674 Hebrew root words used in the Old Testament. (Example: ) The 5,624 Greek root words used in the New Testament. (Example: ) Although the Greek words in Strong's Concordance are numbered 1–5624, the numbers 2717 and 3203–3302 are unassigned due to "changes in the enumeration while in progress". Not every distinct word is assigned a number, but rather only the root words. For example, αγαπησεις is assigned the same number as αγαπατε – both are listed as in Strong's Concordance (αγαπαω). Due to Strong's numbers it became possible to translate concordances from one language into another. Thus, the Russian concordance of 30,000 words from the Russian Thompson Study Bible ("Новая учебная Библия Томпсона", La Buona Novella Inc, 2010, edition made by the Christian society "The Bible for everyone" in St.Petersburg, Russia) is a translation of the English concordance from Thompson Chain-Reference Bible (The New Thompson Study
