Old Testament

The Old Testament is the first major division of the Christian Bible, consisting of the canonical Scriptures written before the birth of Jesus Christ. It forms the theological, historical, and prophetic foundation for the New Testament and the entire redemptive narrative of Scripture.

Comprising 39 books (in the Protestant tradition), the Old Testament records:

• The creation of the world

• The Fall and the spread of sin

• God’s Covenant with Abraham

• The formation and history of Israel

• The law delivered through Moses

• The prophets who called Israel to faithfulness

• And the hope of a coming Messiah

Structure and Divisions

The Old Testament is traditionally divided into three main sections:

1. The Law (Torah or Pentateuch) – Genesis to Deuteronomy

2. The Prophets – Joshua through Kings, and the major/minor prophets

3. The Writings – Psalms, Proverbs, Job, and other poetic and wisdom literature

This threefold structure is preserved in Hebrew Bible tradition (Tanakh: Torah, Nevi’im, Ketuvim) and referenced by Jesus in Luke 24:44.

The English arrangement follows a thematic rather than chronological order:

• Historical books (Genesis–Esther)

• Poetical books (Job–Song of Solomon)

• Prophetical books (Isaiah–Malachi)

Language and Authorship

Most of the Old Testament was written in Biblical Hebrew, with small sections in Aramaic (notably in Daniel and Ezra). It was composed over a period of more than a thousand years, by multiple human authors under divine inspiration (2 Peter 1:21), including:

• Moses (Torah)

• David and Solomon (Psalms, Proverbs, Ecclesiastes)

• Prophets (Isaiah, Jeremiah, etc.)

• Anonymous scribes, chroniclers, and wisdom writers

Despite this diversity, the Old Testament displays profound unity-bound together by the unfolding of God’s covenant promises.

Theological Themes

Major themes woven throughout the Old Testament include:

• Creation and Providence – God as Creator and Sustainer

• Covenant – With Adam, Noah, Abraham, Israel (Mosaic), and David

• Sin and Judgment – Human rebellion and divine justice

• Redemption – The promise of salvation through sacrifice and deliverance

• Messianic Hope – Prophetic anticipation of a coming king and redeemer

• Holiness and Worship – Laws, sacrifices, and the presence of God

These themes find their fulfillment in Christ, who declared that the Law, the Prophets, and the Psalms all testify of Him (Luke 24:27, 44).

Relationship to the New Testament

The Old Testament is not a separate or inferior revelation but the first act of God’s redemptive drama. The New Testament does not replace the Old but fulfills and clarifies it.

• Matthew opens by tracing Jesus’ genealogy to Abraham and David

• Romans and Galatians show that believers in Christ are children of Abraham

• Hebrews interprets the Old Testament priesthood, sacrifices, and tabernacle as shadows of Christ’s work

The Reformation emphasized the unity of Scripture, affirming the Old Testament’s continuing authority for doctrine, ethics, and worship.

Canonical Considerations

While Protestant Bibles contain 39 books, Catholic and Orthodox traditions include additional writings known as the Apocrypha or Deuterocanonical books (e.g., Tobit, Wisdom, 1–2 Maccabees). These are not considered canonical in Reformed theology but are sometimes read for historical context.

The original order and form of many Old Testament books differ in the Masoretic Text, the Septuagint, and other early versions. Nevertheless, the content of the 39 books is affirmed as divinely inspired and inerrant.
