Ok. I thought I had the "Strongest" concordance, but when I picked this one up and looked at it, I realized that I had fallen prey to a marketeer's clever play on words. Nelson's New Strong's Expanded Exhaustive Concordance blow's Zondervan's out of the water. The substantially expanded Greek and Hebrew dictionary definitions alone make this volume indispensible to any student of God's Word who owns a KJV. Like the "Strongest", it has all of the nice extras like a complete topical index of the Scriptures, and convenient alphabetical page markings. It is about twice as thick as Zondervan's concordance, partly because of the 600+ pages of Greek and Hebrew dictionaries(Compared to about 200 in the competitor's volume.), and partly becuase the print is larger (and WAY clearer and easier to read) than Zondervan's. The only thing "stronger" about the competitor's book is a better quality binding. This one isn't bad by any stretch, but Zondervan's lay-flat Smythe sewn binding is definitely better. That being said, I'm planning on giving my other concordance to my brother. This one's a keeper!

I really love this Red Letter Edition as it is very easy to look up the words spoken by Jesus. The Hebrew, Aramic, and Greek dictionaries are simply superb. True, you must read the instructions on how to use it but that holds true for any concordance. Without this indispensable aid you are missing out on the true meaning of the words.
