What Is a Lexicon? How Bible Words Carry Meaning
Short answer: A lexicon is a dictionary of a language, and in Bible study it usually means a dictionary of biblical Hebrew, Aramaic, or Greek. It lists each word as it actually appears in the text, then gives the range of meanings that word can carry, often with the passages where each sense occurs. A lexicon does not tell you what a verse means; it tells you what a word could mean in that language. The work of deciding which sense fits a given sentence belongs to the reader, and that decision must be made from the context of the passage. Nehemiah 8:8 shows the pattern: the law was read clearly, and someone gave the sense so the people understood. A lexicon is one tool that serves that same labour of giving the sense.
Where the Word Lexicon Comes From
The English word lexicon traces back to Greek lexikon, which described a book of words, from lexis, meaning a speaking or a word. In the ancient world, word lists existed for hard or rare terms, but the comprehensive dictionary as we know it is a later development. When you open a modern biblical lexicon, you are holding the fruit of centuries of cataloguing: every occurrence of a Hebrew or Greek word in surviving literature, sorted by form and sense. That cataloguing is ordinary, patient scholarship, not revelation. It is the kind of work that makes careful reading possible for people who never learn the languages themselves.
It helps to see the lexicon as a map rather than a trail. A map shows you that a region contains rivers, ridges, and roads. It does not tell you which road you are standing on. A lexicon shows you that a Greek word can mean to serve, to minister, or to wait on tables. It does not tell you which of those senses Paul intended in a particular sentence. That is why a lexicon entry is a starting point for interpretation, never the conclusion. The entry gives you the options; the verse gives you the choice.
Because of this, the lexicon is closely tied to the doctrine of Scripture. Christians believe the words of the Bible were given by God through human authors writing in real languages to real readers. If the words matter, then knowing what the words meant matters. A lexicon is one way we honour the fact that God chose to speak in Hebrew and Greek rather than dropping a completed English text from the sky. It is a servant of the text, and servants should never be mistaken for masters.
There is also a practical warning built into the word itself. Anyone can flip to a lexicon and find an exciting meaning, then announce that the verse really says something the English reader would never guess. Sometimes this is genuinely helpful, because English translations compress richness that the original carries. Often it is misleading, because the interesting sense may be rare, poetic, or foreign to the passage at hand. The lexicon is most trustworthy in the hands of someone humble enough to be corrected by the context.
Nehemiah 8:8 and the Work of Giving the Sense
The scene is the rebuilt wall of Jerusalem and a gathered crowd. Ezra stands on a wooden platform, and the people ask him to bring the book of the law of Moses. Nehemiah 8:8 records the method: "They read in the book, in the law of God, distinctly; and they gave the sense, so that they understood the reading." Several things are happening at once. The text was read aloud. It was read clearly, not mumbled or rushed. Then a further step followed: someone gave the sense. The Hebrew behind that phrase carries the idea of insight or understanding being supplied to the hearers.
Notice the order. Reading came first, then explanation, then comprehension. The explainers did not replace the text with their own ideas, and they did not leave the people with raw syllables they could not follow. They served the text by opening it. That is precisely the role a good lexicon plays in a modern study. It does not stand in front of the Bible; it stands beside the reader, helping the words land as words rather than as noise. The goal of the whole exercise is stated plainly: the people understood the reading.
This passage is not a mandate for scholarly apparatus, and it would be dishonest to pretend Ezra was handing out dictionaries. The point is broader and more durable: God's word was given to be understood, and understanding is a real task that requires help. Some of that help came from people who knew the language better than the crowd. The same is true today. A lexicon is a modest, unglamorous form of the service described in Nehemiah 8:8, and it aims at the same end, that ordinary listeners and readers would grasp what God has said.
There is a pastoral comfort here. If understanding the Bible required fluency in ancient languages, most believers would be shut out. Nehemiah's crowd was not made of scribes. The reading was public, the explanation was given, and the people went away knowing what they had heard. Tools like lexicons exist so that this pattern continues. They are not a clerical secret. They are part of how the church keeps handing the sense of Scripture to each new generation of readers.
What Entries Actually Contain
A typical biblical lexicon entry begins with the word itself in its original script, then a transliteration so readers who do not know the alphabet can still pronounce and find it. It gives a grammatical identification, such as noun or verb, and a stem or form. Then comes the main body: a numbered list of possible senses, often grouped by how common each is. Good lexicons add the passages or at least the categories of passages where each sense appears, so you can check whether a proposed meaning is typical or rare.
Beyond bare meaning, entries often mark frequency. A word occurring four hundred times is ordinary vocabulary; a word occurring once is called a hapax legomenon, and its meaning may be genuinely uncertain. Honest lexicons say so. They use phrases like probably, perhaps, or of uncertain meaning. When you see such hedging, you are not looking at weakness; you are looking at integrity. The alternative, a confident gloss invented to fill a gap, would be far worse. Learn to read the hedges, because they tell you how much weight a word can bear in your teaching.
Many entries also trace related words. Hebrew and Greek build families of terms from shared roots, and seeing those connections can illuminate a passage. But root connections are easily overused. English has the word understand, and also the word stand; nobody concludes that understanding means standing under something. The same caution applies to biblical languages. A lexicon may list related forms, but shared roots do not guarantee shared meaning in a given sentence. Context still governs.
Finally, entries frequently cite how the word was used in extra-biblical literature, such as everyday Greek documents, the Septuagint, or Jewish writings. This evidence is valuable because it shows how ordinary speakers of the language used the term. It also reminds us that biblical Greek was not a special heavenly dialect. The New Testament writers used the common language of their day, and a lexicon catalogues that ordinary usage so we can read the text the way its first hearers would have.
Why a Lexicon Is Not a Magic Decoder
The most common mistake in word study is treating the lexicon as a source of hidden meanings that trump the plain sense of a verse. This is sometimes called the root fallacy, or illegitimate totality transfer: taking every possible sense a word can carry and dumping all of them into one occurrence. A word does not mean everything it could ever mean in every place it appears. When Acts 17:11 says the Bereans were "examining the Scriptures daily to see whether these things were so," they were testing a message against a text, not mining words for astonishing new senses.
Related to this is the danger of choosing the rarest sense because it sounds more spiritual. If a Greek word usually means to serve but once, in a different author, means to be a slave, that does not make every occurrence about slavery. The usual sense is usually right. Lexicons typically list senses in order of frequency for a reason. To reach past the ordinary meaning, you need positive evidence from the immediate context: the grammar, the argument, the surrounding sentences, the flow of the book. Without that evidence, the unusual sense is speculation dressed as research.
Time pressure makes this worse. A teacher preparing a lesson can find an interesting entry Tuesday night and preach it Sunday with great confidence. The congregation cannot check the claim without the same tools, and the claim sounds learned. That is a recipe for error. Better to say from the pulpit, this word can carry several senses and here the context points to this one, than to declare a novel meaning as though the lexicon had settled the matter. The people in Nehemiah 8:8 needed the sense, not a spectacle.
None of this makes lexicons useless. It makes them tools that require skill. A hammer is not at fault when someone uses it on a screw. The remedy is not to abandon word study but to pair it with grammar, context, and the wider teaching of Scripture. The best protection against misuse is a habit of asking, would the original hearers have understood it this way, and does the rest of the passage support it.
How to Use a Lexicon Well in Study
Start with the text, not the tool. Read the passage in a good English translation, then perhaps in a second translation, and note where they differ. Difference often signals a word or phrase with a range of meaning, and that is exactly where a lexicon earns its keep. Only then look up the term. You are checking a hypothesis against evidence, not hunting for a sermon illustration. This order keeps the passage in charge and the reference book in service.
When you look up the word, read the whole entry rather than the first line. Note the range, the frequency, and any hedging. Ask which sense the immediate sentence requires. Consider the grammar: is the word a command, a participle, a noun with a preposition? Meaning lives in sentences, not in isolated terms. Second Timothy 2:15 speaks of a workman "properly handling the Word of Truth," and proper handling includes not ripping words out of their sentences. A lexicon used this way sharpens reading rather than replacing it.
Then check the wider canon. Does your proposed sense fit the book, the author, and the rest of Scripture? Psalm 119:105 says, "Your word is a lamp to my feet, and a light for my path." The image is guidance for walking, and it assumes the word can be understood well enough to direct steps. If your word study produces a meaning that no faithful reader across the centuries has ever seen, be suspicious of your study rather than of the church. Novelty is not the same as insight.
Finally, keep proportion. Most words do not need a lexicon; they need attention. Use the tool when a word is repeated, when a translation difference puzzles you, when a term is theologically loaded, or when a passage turns on a single phrase. Hebrews 4:12 says the word of God is "living and active," and its power does not depend on your access to scholarly apparatus. The lexicon is a small lamp beside a much greater light. Hold it up, then look at the road.
Tools Differ and So Do Teachers
Not all lexicons are equal. Older works such as Strong's numbering system are widely available and helpful for locating words, but the definitions are brief and sometimes dated. Fuller lexicons, such as those by Brown, Driver, and Briggs for Hebrew or Bauer and later revisers for Greek, offer more senses and more evidence. Newer works incorporate more papyri and inscriptions, so they sometimes correct older conclusions. Using one tool alone is like consulting one witness. Comparing two or three gives you a sense of where the evidence is solid and where scholars genuinely disagree.
Faithful Christians differ on how much weight to give scholarly reconstructions, how to handle disputed readings, and how far word studies should shape preaching. Those differences are real and should be described honestly rather than papered over. What unites careful teachers is a commitment to let the text govern. A lexicon can be a genuine means of grace when it helps a reader see what the author wrote, and a genuine snare when it becomes a way to impress people with information the passage never claimed.
Biblical fidelity check
Nehemiah 8:8 establishes that the law was read distinctly and that the sense was given so the people understood. It does not establish a command to own a lexicon, a method for word studies, or a claim that Hebrew and Greek carry secret meanings hidden from ordinary readers. The passage describes a public reading with explanation. It also does not tell us who did the explaining, how long it took, or what technique they used. Anyone who builds a whole doctrine of Bible study from this single verse is pressing it beyond what it says.
A common misreading takes the phrase about giving the sense and turns it into a warrant for finding a deeper meaning beneath the plain text. That is wrong because the aim stated in the verse is understanding the reading, not moving past it. The Hebrew idea is insight into what was read, not a second, hidden message. The same error appears today when a lexicon entry is used to overturn what a passage plainly says in context. The tool then competes with the text instead of serving it.
Other passages that speak to Nehemiah 8:8
Several passages reinforce the pattern of careful reading and diligent handling. Acts 17:11 commends the Bereans for receiving the word with readiness and examining the Scriptures daily, a model of testing teaching against the text. Second Timothy 2:15 calls for diligence in handling the Word of Truth properly, which includes attention to words and their meanings. Hebrews 4:12 describes the word as living and active and able to discern the heart, reminding us that the goal of study is not information but transformation. Psalm 119:105 pictures the word as a lamp and light for the path, which assumes it can be understood well enough to guide. For more on these themes, see What does 2 Timothy 1:7 mean about fear? What does Hebrews 11:1 mean by faith? What does Psalm 23 mean for Christians today? and What does Psalm 46:10 mean by be still?
Frequently asked questions
Do I need to know Hebrew or Greek to use a lexicon?
No. Most lexicons are arranged so you can look up a word by its transliteration or by a number keyed to a concordance. You will not be able to parse verbs or judge grammar without some training, and that limits how far you can go. But you can still check a word's range of meaning and see how often a sense occurs. Use the tool for what it offers, stay humble about what it cannot do, and lean on good translations and trusted teachers for the rest.
Is a lexicon the same as a concordance or a commentary?
No. A concordance lists where a word appears; it is an index, not a dictionary. A lexicon gives the meanings and range of a word in its original language. A commentary explains a whole passage or book, weighing grammar, history, and theology together. Each serves a different purpose. A concordance helps you find occurrences, a lexicon helps you understand a term, and a commentary helps you follow an argument. Used together, they keep a word from being isolated from its sentence and paragraph.
Can a lexicon ever change what a verse means?
A lexicon can correct a wrong impression and clarify a phrase, but it should not overturn the plain sense of a passage read in context. When a study produces a meaning no faithful reader has seen, suspicion is warranted. The Bereans in Acts 17:11 examined the Scriptures to see whether the message was so, which means the text itself was the standard. Word tools serve that standard. They help you see what is written, and the written text, understood in context, remains the authority.
