What is a lexicon?
Biblical language dictionaries and lexicons are another key resource used when writing an exegetical paper or when simply curious about the origin of a word's use in it's original language. There are a wide variety of these with some single volume resources and others spanning many books.
Each dictionary or lexicon may be ordered differently. Some are designed for you to look up your word or term in English while others are ordered alphabetically in the original language. A good place to start when you don't know how to find you work in a lexicon is by using the index. Many volumes that are in order in Greek or Hebrew will provide a subject/term index in English to further assist you in locating your word. Many also use Strong's or G.K. numbers to help you find your concept.
If you find you are having difficulty locating your word in one of these resources, feel free to ask a librarian for help!
