About KJV Study

A comprehensive resource for serious study of the Holy Scriptures

KJV Study was created by Kenneth Reitz, a software developer known for his work in open source software. What began as a personal study tool has grown into a comprehensive resource for serious study of the King James Bible, serving readers around the world. The goal is not merely academic knowledge but transformative encounter with the living God through His written Word. "Thy word have I hid in mine heart, that I might not sin against thee" (Psalm 119:11).

Built upon the 1769 Cambridge Edition of the King James Version—the translation that has shaped English-speaking Christianity for over four centuries—this site provides deep, scholarly, and theologically faithful resources for both the beginning reader and the seasoned student of God's Word. We believe serious Bible study should be accessible to all believers, not locked behind paywalls or reserved for those with access to theological libraries. Every commentary, cross-reference, and language tool here is freely available, reflecting our conviction that God's Word belongs to God's people.

Theological Convictions

KJV Study stands firmly within historic Christian orthodoxy, committed to the faith once delivered to the saints. Jude exhorts believers to "earnestly contend for the faith which was once delivered unto the saints" (Jude 1:3). This faith is not evolving or developing but fixed and complete in the apostolic deposit. Our commentary reflects careful engagement with the original languages, ancient Near Eastern context, and the theological heritage of the church across the centuries.

The Inerrancy & Sufficiency of Scripture

We confess that the sixty-six books of the Old and New Testaments are the inspired, infallible, and inerrant Word of God—theopneustos (θεόπνευστος), "breathed out by God" (2 Timothy 3:16). The compound θεόπνευστος joins θεός (God) and πνέω (to breathe). Scripture's origin is divine exhalation—God breathing out His words through human authors. This is not mere dictation but organic inspiration preserving both divine authority and human personality. Scripture is not merely a human witness to divine truth; it is divine truth, wholly trustworthy in all it affirms. As the psalmist declared, "Thy word is a lamp unto my feet, and a light unto my path" (Psalm 119:105)—the Hebrew dāḇār (דָּבָר) signifying not mere information but God's active, living communication that accomplishes His purposes (Isaiah 55:11). We reject both rationalistic liberalism that denies supernatural revelation and mystical subjectivism that seeks guidance apart from the written Word. Scripture alone is sufficient for life and godliness.

The Triune God

We worship one God eternally existing in three persons—Father, Son, and Holy Spirit—distinct in personhood yet one in essence, will, and glory. The Shema declares "The LORD our God is one LORD" (Deuteronomy 6:4), using אֶחָד (echad)—a unity that can encompass plurality, as when "they two shall be one flesh" (Genesis 2:24). Matthew 28:19 reveals that baptism is administered "in the name" (singular τὸ ὄνομα/to onoma—not "names") of the Father, Son, and Holy Spirit, expressing their essential unity while acknowledging their distinct persons. God is sovereign over all creation, providence, and redemption, working all things according to the counsel of His will (Ephesians 1:11). His purposes cannot be thwarted; His decrees stand forever.

Substitutionary Atonement

We affirm that Christ's death on the cross was a true substitutionary sacrifice, satisfying divine justice on behalf of sinners. The Day of Atonement prefigured this reality: the scapegoat bearing Israel's sins into the wilderness (Leviticus 16) typified Christ who "bare our sins in his own body on the tree" (1 Peter 2:24). Isaiah 53:5 proclaims: "He was wounded for our transgressions, he was bruised for our iniquities"—the Hebrew mecholal (מְחֹלָל) meaning pierced through, fatally wounded, while the preposition min (מִן) indicates substitution: His wounds came "because of" our sins. The chastisement of our peace was upon Him; by His stripes we are healed. This is penal substitution: Christ received the penalty we deserve so that we might receive the peace He deserves.

Salvation by Grace Alone

We confess that salvation is entirely of grace, through faith, in Christ alone (Ephesians 2:8-9). The Greek χάρις (charis) signifies unmerited favor—God's gracious disposition toward those who deserve judgment. Faith itself is a gift (Philippians 1:29), ensuring that no flesh may glory in His presence. No one can earn salvation through works; it is the gift of God. All have sinned and fall short of God's glory (Romans 3:23), standing justly condemned apart from Christ. Yet God justifies the ungodly through faith, imputing Christ's perfect righteousness to those who believe (Romans 4:5, 2 Corinthians 5:21). From first to last, salvation is the Lord's work.

The Eternal Deity of Christ

With John's Gospel, we confess: "In the beginning was the Word, and the Word was with God, and the Word was God" (John 1:1). John's use of λόγος recalls both Hebrew dāḇār (the creative, powerful word of God) and Greek philosophical concepts of cosmic reason—yet transcends both in identifying this Word as a divine Person who "became flesh and dwelt among us" (John 1:14). The Greek Logos (λόγος) identifies Christ as God's eternal self-expression—not a created being but the Creator Himself through whom all things were made. The imperfect tense ēn (ἦν, "was") indicates continuous existence: when time began, the Word already existed. He is fully God and fully man, the only mediator between God and humanity (1 Timothy 2:5), the promised Messiah in whom all God's covenant promises find their "Yes" and "Amen" (2 Corinthians 1:20).

Christocentric Interpretation

All Scripture testifies of Christ (John 5:39). From bereshit (בְּרֵאשִׁית, "In the beginning") to the final Amen of Revelation, the Bible reveals Jesus Christ as the center of redemptive history. On the Emmaus road, Christ expounded "in all the scriptures the things concerning himself" (Luke 24:27). The law, prophets, and writings all point to Him—in type, prophecy, and promise. We interpret every passage in light of its immediate literary and historical context, the whole counsel of God, and the redemptive arc that culminates in Christ's person and work. Our commentary engages the original Hebrew and Greek, ancient Near Eastern backgrounds, and the testimony of faithful interpreters throughout church history.

We encourage every reader to be like the Bereans, examining the Scriptures daily to test all teaching (Acts 17:11). Soli Deo Gloria.

Data & Sources

KJV Study stands on the shoulders of faithful scholars and translators across the centuries. We gratefully acknowledge:

The King James Bible

The 1769 Cambridge Edition, also known as the "Blayney Edition," represents the refined and standardized text of the Authorized Version first published in 1611. Benjamin Blayney's revision corrected printing errors and standardized spelling. The 1611 text was produced by 47 scholars in six companies meeting at Westminster, Cambridge, and Oxford over seven years. This translation, produced by 47 scholars working in six committees, drew upon the best Hebrew and Greek manuscripts available, the Latin Vulgate, and earlier English translations including Tyndale, Coverdale, and the Geneva Bible. Its enduring influence on English language and literature remains unparalleled.

Cross-References

Our cross-reference data derives from the Treasury of Scripture Knowledge, a monumental 19th-century work containing over 500,000 Scripture references. The TSK was compiled over thirty years by R.A. Torrey and others, building upon earlier works like Thomas Scott's commentary and Canne's marginalia. It remains the most comprehensive cross-reference resource ever published. This data, curated and refined by OpenBible.info, reveals the remarkable interconnectedness of biblical texts—how prophecy finds fulfillment, how types foreshadow antitypes, and how themes weave through the entire canon.

Original Language Resources

Strong's Exhaustive Concordance (1890), compiled by James Strong and over 100 colleagues, remains an indispensable tool for accessing the Hebrew (ʿIḇrîṯ) and Greek (Koinē) vocabulary underlying the English text. Strong assigned a unique number to each Hebrew and Greek root word, enabling those without language training to trace English words to their originals. The system revolutionized Bible study accessibility. Our interlinear data, providing word-by-word analysis with parsing and morphological information, enables readers without formal language training to engage meaningfully with the original texts.

Commentary

All verse commentary is original content written specifically for KJV Study with the assistance of artificial intelligence, drawing upon the work of commentators ancient and modern—from the Church Fathers through the Reformers to contemporary evangelical scholarship. Each entry is carefully reviewed and curated to illumine the text's meaning in its original context while drawing out its enduring theological significance and practical application.
