Blue Letter Bible Tutorial: Word Studies, Commentaries, and Hebrew/Greek Tools
Master the Blue Letter Bible with our deep-dive tutorial. Learn how to conduct word studies, access commentaries, and use Hebrew and Greek tools to enrich your personal study.

In our modern era, we are blessed with an unprecedented accessibility to the Word of God. No longer are the deep riches of the original biblical languages reserved only for those with a seminary education or a library full of expensive, dusty volumes. The Blue Letter Bible (BLB) has emerged as one of the most powerful, user-friendly, and free digital platforms available to the global Church. It serves as a comprehensive study suite designed to help believers 'rightly handle the word of truth' (2 Timothy 2:15) by providing direct access to the Hebrew and Greek manuscripts, cross-references, and historical commentaries. For anyone looking to move beyond a surface-level reading of the text, mastering this tool is a transformative step in their spiritual journey.
The beauty of the Blue Letter Bible lies in its ability to bridge the gap between the English translation and the original intent of the biblical authors. While we can trust our modern translations, there is a distinct spiritual depth found in exploring the nuances of the original languages. Whether you are curious about the specific type of 'love' Jesus refers to in the Gospels or you want to understand the cultural context of an Old Testament prophecy, BLB provides the keys to unlock these insights. This tutorial is designed to take you by the hand and show you how to navigate the most vital features of the site, from basic navigation to advanced word studies and scholarly research.
Navigating the Blue Letter Bible Interface
When you first arrive at the Blue Letter Bible homepage, the layout is designed for immediate engagement with the Scriptures. At the top of the page, you will find a prominent search bar where you can enter a specific verse reference, such as 'John 3:16', or a keyword like 'grace' or 'covenant'. This search function is the primary gateway to the rest of the site’s tools. Once you have navigated to a specific chapter, you will notice various buttons next to every verse. These options are the heart of the platform, offering access to the Interlinear, Bibles (to compare translations), Cross-References, and Commentaries. Familiarizing yourself with these small icons is the first step toward a deeper study experience.
A standout feature of the Blue Letter Bible is its 'Compare' function. By clicking the 'Bibles' tab next to a verse, you can see how different translation committees have rendered the same passage. This is incredibly helpful because no single English word can always capture the full weight of a Hebrew or Greek term. Seeing the English Standard Version (ESV) alongside the King James Version (KJV) or the New Living Translation (NLT) can highlight nuances in the text that you might have otherwise missed. It encourages a meditative approach to reading, as we see in Psalm 1:2, where the blessed person 'meditates on his law day and night.'Comparing translations is a practical way to begin that process.
Mastering the Interlinear: Hebrew and Greek Tools
The most powerful feature for many students of the Word is the Interlinear tool. When you click the 'Tools' button next to a verse and select 'Interlinear,' you are presented with a detailed breakdown of the original language. The Blue Letter Bible displays the English words, the original Hebrew (for the Old Testament) or Greek (for the New Testament), and the corresponding Strong's Concordance numbers. This allows someone with zero knowledge of ancient languages to see the 'building blocks' of the verse. It provides a direct link to the Lexicon, which is a dictionary for these ancient words, providing definitions that are often much richer than their simple English equivalents.
Using the interlinear tool helps prevent us from importing modern definitions into ancient texts. For example, when we read the word 'blessed' in the Beatitudes (Matthew 5:3-12), using the Greek tool reveals the word 'makarios,' which implies a divine satisfaction and well-being that is independent of external circumstances. By seeing the original word, the reader gains a clearer picture of Jesus' radical teaching. This level of study allows the Holy Spirit to sharpen our understanding, ensuring that we are hearing the Word as it was intended to be heard by its original audience. It brings a sense of awe to recognize how meticulously God inspired every jot and tittle of His Word.
Conducting a Professional Word Study
A deep word study can change your entire perspective on a passage of Scripture. On the Blue Letter Bible, once you click a Strong’s number in the Interlinear view, you are taken to a dedicated Lexicon page. This page is a goldmine of information. It includes a 'mounce' or 'thayer' definition, but most importantly, it shows the 'Concordance Results.' This is a list of every single time that specific Greek or Hebrew word is used throughout the entire Bible. By clicking through these verses, you can see how the biblical authors used a specific term in various contexts, which is often the best way to define a word's biblical meaning.
Consider the word 'remnant' in the Old Testament. By following its Hebrew root through the Blue Letter Bible, you can see God’s consistent pattern of preserving a faithful few throughout the history of Israel. This thematic consistency becomes clear as you trace the word across different books. This method of 'letting Scripture interpret Scripture' is one of the safest and most enlightening ways to study. It prevents us from building a theology on a single verse and instead helps us see the grand narrative of God’s redemptive work. As Colossians 3:16 encourages, it allows the 'word of Christ to dwell in you richly.'
Leveraging Historical and Modern Commentaries
While personal study and original language tools are vital, we are not meant to study in a vacuum. God has gifted the Church with teachers throughout the ages (Ephesians 4:11-12). The Blue Letter Bible provides free access to an enormous library of commentaries from both historical giants and modern scholars. By clicking the 'Commentaries' tab next to a verse, you can find the writings of Matthew Henry, Charles Spurgeon, and J.C. Ryle, alongside contemporary teachers like David Guzik or John MacArthur. These resources provide cultural context, historical background, and theological synthesis that can clarify difficult or obscure passages.
Using commentaries correctly requires a balance of humility and discernment. It is always best to use the Blue Letter Bible to study the text yourself first, asking the Holy Spirit for insight. Once you have made your own observations, consult the commentaries to see if your findings align with the historic witness of the Church. This 'safety in the multitude of counselors' (Proverbs 11:14) protects us from novel or errant interpretations. Commentaries are especially helpful for understanding the 'why' behind certain ancient laws or the specific historical threats facing a local church in one of the Epistles, making the ancient text feel vibrantly relevant to our lives today.
The Importance of Cross-References and Treasury of Scripture Knowledge
One of the most underutilized but essential tools on the Blue Letter Bible is the Treasury of Scripture Knowledge (TSK). This is a massive collection of cross-references that link verses together based on shared themes, words, or events. When you select the 'Cross-References' tab, you are shown other parts of the Bible that shed light on your current passage. For instance, if you are studying the sacrifice of Isaac in Genesis 22, the cross-references will point you toward Hebrews 11 and James 2, showing you how the New Testament authors looked back on that event as a model of faith.
This tool highlights the supernatural unity of the Bible. Despite being written by over 40 authors over 1,500 years, the Bible tells one cohesive story. Using the Blue Letter Bible's cross-referencing system helps you see these threads. It reminds us that no part of the Bible exists in isolation. As you follow these links, you begin to see 'the whole counsel of God' (Acts 20:27). It turns your study from a look at a single piece of a puzzle into an appreciation for the entire masterpiece of God’s revelation, strengthening your confidence in the divine inspiration and sufficiency of the Scriptures.
Using the Dictionary and Encyclopedia Tools for Context
To truly understand the Bible, we must sometimes understand the world in which it was written. The Blue Letter Bible includes several Bible dictionaries and encyclopedias, such as the International Standard Bible Encyclopedia (ISBE) and Easton’s Bible Dictionary. These are invaluable when you encounter a term, city, or name you don't recognize. If you are reading about the 'Pharisees' or 'Corinth,' a quick search in the dictionary section will give you the historical background, social status, and geographical significance of those subjects. This context often changes how we perceive the narrative or the instruction being given.
For example, knowing the geographical difficulty of the road from Jerusalem to Jericho adds weight to the Parable of the Good Samaritan (Luke 10:25-37). Using the Blue Letter Bible to look up the topographical context allows the reader to realize just how dangerous that journey was for the traveler. These tools turn 'black and white' text into a 'technicolor' experience. By grounding our study in historical reality, we guard against overly allegorizing the text and instead find the solid, literal truth that God intended to communicate. This disciplined approach builds a firm foundation for our faith and a more accurate application of biblical principles to our modern lives.
Final Thoughts
The Blue Letter Bible is more than just a digital version of the Holy Scriptures; it is a bridge that connects the modern reader to the ancient, eternal wisdom of God's Word. By learning to navigate its original language tools and scholarly resources, you are not just gathering information, but positioning yourself to be transformed by the depth of God's truth. As you open the site today, remember that the goal of all study is to know Christ more intimately and to walk in obedience to His commands.
Whether you are a seasoned pastor or a new believer just beginning your journey in the faith, tools like BLB are a gift to the global church. May your time spent in word studies, reading commentaries, and exploring the original Hebrew and Greek text bear much fruit in your life. As the Psalmist prayed in Psalm 119:18, may the Lord open your eyes that you may behold wondrous things out of His law. Happy studying, and may God bless your pursuit of His truth.

Frequently Asked Questions
Is Blue Letter Bible free to use for all features?
Blue Letter Bible remains a free resource for the global body of Christ. It is supported by the generous donations of users who value its mission to provide high-quality study tools to everyone regardless of their financial status. While they offer a mobile app and a comprehensive website, all their core features including lexicons, commentaries, and dictionaries are accessible without a subscription fee, ensuring that the Word of God is not hindered.
Can I access Blue Letter Bible on my mobile phone?
Yes, the Blue Letter Bible app is available for both iOS and Android devices. While the interface is slightly different from the desktop website, it includes the same powerful tools such as the Interlinear feature, Strong’s Concordance, and a vast library of audio and written commentaries. It is an excellent way to keep your deep-study tools with you wherever you go, perfect for personal devotions during a commute or quick reference during a small group discussion.
How do I perform a word study using Strong’s numbers on BLB?
The 'Interlinear' tab is your gateway. When you select a verse, click the 'Interlinear' button to see the English words alongside their original Hebrew (Old Testament) or Greek (New Testament) counterparts. Each original word is assigned a Strong’s number. Clicking this number opens the Lexicon, providing the definition, phonetic pronunciation, and every other instance where that specific word appears in the Bible, allowing for a comprehensive thematic study.
Should I read commentaries before or after my own study?
Commentaries provide historic and scholarly context, but they are not inspired like Scripture. When using the 'Commentaries' tab on BLB, you can access insights from trusted theologians like Matthew Henry or Charles Spurgeon. It is best practice to study the biblical text yourself first, asking the Holy Spirit for guidance. Afterward, use commentaries to see how the Church has historically understood the passage, which can help guard against personal misinterpretations.
How can I see how a word is used in other parts of the Bible?
To see the same word in different contexts, go to the Lexicon page for that specific word (via the Strong’s number). Scroll down to the section titled 'Concordance Results.' This list shows every verse in the Bible where that exact root word is used. This is incredibly helpful for understanding 'semantic range'—how a word like 'agape' (love) is used in different scenarios, which provides a more holistic view of its biblical meaning.
