What's a Bible Lexicon? Bible lexicons provide definitions and meaning of Biblical words found in the original New Testament Greek and Old Testament Hebrew languages of the Holy Bible. Lexicons help in understanding the origins and root meaning of the ancient language. Additional, lexicons give the context and cultural meaning intended by the authors. Using the online King James Version or New American Standard lexicon with Strong’s Concordance numbers provides a detailed understanding of the Hebrew and Greek language used in the Bible.
