A Concordance is used mainly for word studies, as explained in the article on Tools. For the same purpose I would prefer to use the “universal search” box on the left side of the net.bible.org page (by doing a search for the same word I would look up in a concordance). For word studies, one can also use the KJV with Strong’s links from the same page.
- For a more normal (if smaller) concordance, there is one at the ibs.org site.
- There are Greek and Hebrew Lexicons at http://bible.crosswalk.com/Lexicons/. The Greek Lexicon will accomodate searching on English words and Strong’s numbers as well as Greek words.
- A good choice for offline use is a PDF-format concordance you can download from http://septuagint-interlinear-greek-bible.com/ and free updates are still available for download there as of this writing (May 2008).
