It is a number 1 "go to" in Bible study. Our modern word meanings don't always mean the same as our Hebrew and Greek words. I recommend it to anyone wishing to understand words meanings in the Bible terms they were meant to mean.
This is one of the best reference books I have found for those who do not know Greek or Hebrew and desire to understand the meanings of passages in Scripture that are difficult to understand, especially when different versions of the Bible are read. For example, John 9:31, where we read, "Now we know that God heareth not sinners. . ." If God is omniscient, then He must "hear" all, so how does this work? Using Strong's Concordance, the reader reads that the meaning of "hear" in this instance is "to give audience," making the verse understandable and consistent with other teachings in the Bible. A great book at a great price.
