Why This Matters

The Old Testament isn't just ancient history—it's the foundation for everything you'll encounter in Christian theology. When you study these books, you're learning the vocabulary, concepts, and narrative arc that the New Testament assumes you already know. Understanding covenant, law, prophecy, and wisdom as literary and theological categories will help you recognize how early Christians interpreted Jesus as the fulfillment of these traditions.

You're being tested on more than titles and authors. Exams will ask you to identify how different genres function, what theological themes connect across books, and why certain texts became central to Christian interpretation. Don't just memorize which book contains the Ten Commandments—know what the Law represents in Israelite identity and how Christians later reinterpreted it. Each book below illustrates a specific genre and theological purpose that shaped the Christian worldview.


Torah: The Foundation of Law and Covenant

The first five books—called the Torah (Hebrew) or Pentateuch (Greek)—establish the core narrative and legal framework for everything that follows. These texts define Israel's identity through stories of origin, liberation, and divine instruction.

Genesis

  • Creation and fall narratives—establishes the theological problem (sin, alienation from God) that the rest of Scripture addresses
  • Patriarchal covenants with Abraham, Isaac, and Jacob introduce the promise-fulfillment pattern central to biblical theology
  • Joseph cycle explains how Israelites ended up in Egypt, setting up the Exodus narrative

Exodus

  • Liberation from Egypt becomes the defining event of Israelite identity—referenced throughout the Old and New Testaments
  • Ten Commandments (Decalogue) provide the ethical core of the covenant, distinguishing apodictic law (absolute commands) from case law
  • Tabernacle instructions establish patterns of worship, sacrifice, and divine presence that Christians later apply to Jesus

Deuteronomy

  • Moses' farewell speeches reinterpret the law for a new generation about to enter the Promised Land
  • Shema ("Hear, O Israel")—the command to love God with all your heart—becomes the greatest commandment Jesus quotes
  • Blessings and curses framework explains Israel's later history as consequence of covenant faithfulness or disobedience

Compare: Genesis vs. Exodus—both establish covenant relationships, but Genesis focuses on family promises (land, descendants) while Exodus establishes national identity through law and liberation. FRQs often ask how covenant develops across these books.


Historical Books: Monarchy and Its Consequences

These narratives trace Israel's political development from tribal confederation to kingdom to exile. They interpret history theologically, showing how faithfulness to God determines national flourishing or disaster.

Samuel (1 & 2)

  • Transition to monarchy—Samuel anoints first Saul, then David, raising questions about human kingship versus divine rule
  • Davidic covenant promises David's dynasty will endure forever—Christians interpret this as fulfilled in Jesus
  • David's complexity (military hero, adulterer, repentant sinner) models how biblical figures are portrayed with moral ambiguity

Kings (1 & 2)

  • Solomon's temple represents the height of Israelite worship, but his foreign wives introduce idolatry
  • Kingdom division (Israel/north vs. Judah/south) after Solomon creates the political context for the prophets
  • Deuteronomistic evaluation—each king judged by faithfulness to exclusive worship of Yahweh, explaining exile as divine judgment

Compare: Samuel vs. Kings—both cover monarchy, but Samuel focuses on establishing kingship (origin stories of Saul and David) while Kings evaluates generations of rulers against covenant standards. Know this distinction for questions about biblical historiography.


Prophetic Literature: Judgment, Hope, and Messianic Expectation

Prophets served as covenant prosecutors, calling Israel back to faithfulness and announcing consequences. Their oracles combine immediate historical critique with visions of future restoration that Christians read as pointing to Christ.

Isaiah

  • Three historical contexts—scholars identify material addressing 8th-century Assyrian threat, Babylonian exile, and post-exilic restoration
  • Servant Songs (especially Isaiah 53) describe a suffering figure Christians identify as Jesus—among the most quoted OT texts in the NT
  • Messianic prophecies ("a virgin shall conceive," "Prince of Peace") appear in Christmas narratives and theological arguments for Jesus' identity

Jeremiah

  • New covenant prophecy (Jeremiah 31:31-34)—God will write the law on hearts, not stone; directly quoted in Hebrews as fulfilled in Christ
  • Temple sermon challenges false security in religious institutions, a theme Jesus echoes when cleansing the temple
  • Confessions of Jeremiah reveal prophetic suffering and doubt, modeling lament as faithful response to crisis

Compare: Isaiah vs. Jeremiah—both major prophets addressing national crisis, but Isaiah emphasizes royal/messianic hope while Jeremiah stresses new covenant and interior transformation. If asked about Christian use of prophecy, these are your primary examples.


Wisdom Literature: Living Faithfully in God's World

Wisdom books address universal human questions—suffering, meaning, practical ethics—rather than Israel's specific history. They represent a more philosophical tradition that complements law and prophecy.

Proverbs

  • "Fear of the Lord" as wisdom's foundation—not terror, but reverent acknowledgment of God's authority over all life
  • Practical instruction on speech, work, relationships, and money offers ethical guidance without explicit reference to covenant or law
  • Personified Wisdom (Lady Wisdom in chapters 1-9) speaks as divine agent present at creation—Christians connect this to Christ as Logos

Job

  • Theodicy problem—why do the righteous suffer?—challenged through dialogue between Job and friends who assume suffering indicates sin
  • Divine speeches (chapters 38-41) answer not with explanation but with overwhelming display of God's creative power and wisdom
  • Restoration ending remains debated: does it resolve the problem or complicate it? Expect questions about how Job challenges simple reward/punishment theology

Psalms

  • Genre diversity—laments, hymns, royal psalms, wisdom psalms—makes this the most versatile book for worship and prayer
  • Davidic attribution (traditional, though scholars debate actual authorship) connects psalms to Israel's ideal king
  • Messianic interpretation—Psalm 22 ("My God, why have you forsaken me?"), Psalm 110 ("sit at my right hand") quoted extensively in NT as referring to Jesus

Compare: Proverbs vs. Job—both wisdom literature, but Proverbs assumes orderly moral universe (righteousness leads to prosperity) while Job interrogates that assumption. This tension is frequently tested.

Self-Check Questions

  1. Which two books contain covenant promises that Christians interpret as fulfilled in Jesus, and what specifically does each promise?

  2. Compare how Proverbs and Job approach the relationship between righteousness and prosperity. Why might the Bible include both perspectives?

  3. If an exam asks you to explain how the Old Testament prepared for Christian theology, which three books would you choose and why? (Hint: think genre diversity—law, prophecy, wisdom.)

  4. What distinguishes the Davidic covenant (Samuel) from the Sinai covenant (Exodus)? How do these different covenant types shape expectations about Israel's future?

  5. Identify two Old Testament passages that the New Testament quotes as referring to Jesus. From which books do they come, and what do they claim about the Messiah?
