Strong's Concise Concordance and Vine's Concise Dictionary of the Bible....

A multi-purpose Bible study resource tool. All the essentials you need to study the biblical text without having to know Hebrew or Greek. Provides definition, explanation, and concordance entries. Dr. James Strong, formerly professor of exegetical theology at Drew Theological Seminary, spent more than thirty-five years preparing his landmark concordance. First published in 1890 with the help of more than one hundred colleagues, Strong's remains the definitive concordance compiled on the King James Version of the Bible. W. E. Vine, M.A. (1873-1949) was a classical scholar, skilled expositor, and a trustworthy theologian. Recognized internationally for his outstanding Greek scholarship, his Expository Dictionary of New Testament Words, first published in 1939, represents the fruit of his lifetime labors and is an unsurpassed classic in its field.
