Why does God command violence in OT?
Why does God command violence in the Old Testament?

Historical and Cultural Context

In the accounts of the Old Testament, readers encounter passages where God commands acts of violence directed against certain nations or peoples. These commands appear within a distinct historical framework, primarily situating Israel among other ancient Near Eastern cultures. Archeological findings at sites like Hazor and Jericho have provided cultural background that illuminates the practices and level of moral corruption among the surrounding nations. Although archaeologists have varying interpretations of the evidence, the destruction layers at Hazor and the collapsed walls at Jericho point to significant military conflict that aligns with the biblical narrative (Bryant G. Wood, "Did the Israelites Conquer Jericho? A New Look at the Archaeological Evidence," Biblical Archaeology Review, 1990).

Political and social norms of that time reveal that warfare, conquest, and the defense or expansion of territory were common, albeit brutal by modern standards. In this wider cultural setting, the ancient Hebrew texts depict God issuing commands concerning warfare, but with specific moral and theological reasons that will be explored below.


Divine Justice and Judgment Against Evil

A primary assertion throughout Scripture is that God’s holiness necessitates justice against pervasive evil. In Genesis 15:16, it is stated that the iniquity of the Amorites had not yet reached its full measure, indicating that centuries of increasing unrighteousness preceded the eventual judgment. This reveals a principle: God’s commands in the Old Testament are consistently tied to moral reckoning against entrenched wickedness.

In some instances, the nations targeted for destruction were exceptionally corrupt—engaging in child sacrifice, widespread violence, and idolatry. For example, in Leviticus 18:21–25, practices like child sacrifice to Molech and other detestable acts are identified as reasons the land itself would “vomit out its inhabitants.” Ancient documents from the region, such as inscriptions discovered in Carthage (reflecting Phoenician culture related to Canaan), allude to sacrificial practices comparable to those described in Scripture. These finds, though fragmentary, corroborate the intensity of depravity that the Old Testament depicts.


Protection of the Covenant Community

God’s commands to eliminate certain nations can also be understood as a safeguard designed to preserve the lineage and spiritual fidelity of the community through whom the Messiah would come (Genesis 12:3). The biblical narrative shows Israel as the community chosen to bring blessing to all the families of the earth. Ensuring that they were not overtaken by extreme idolatry and destructive practices was crucial for the eventual arrival of the Savior promised in the Scriptures.

Deuteronomy 20:16–18 prescribes that Israel should remove Canaanite tribes so they would not teach the Israelites “all the abominations they have done for their gods.” The aim was not about ethnic cleansing for its own sake but rather preventing corrupt religious practices from penetrating and distorting Israel’s monotheistic worship. This is consistent with the broader biblical theme that idolatry corrupts not only spiritual allegiance but also morality, leading to widespread harm.


Human Free Will and the Delayed Judgment

Throughout Scripture, God’s character is also depicted as longsuffering and merciful, delaying judgment to give opportunities for repentance. The Canaanites had centuries (Genesis 15:16) before judgment fell. In the historical record of Nineveh’s repentance at the preaching of Jonah (Jonah 3:6–10), there is an example of a pagan society turning from evil and thus averting judgment for a time. This pattern underscores that violent judgment in the Old Testament is not an indiscriminate act but rather a last measure against unrepentant cultures that had reached profound levels of corruption.


Specificity and Limitation of the Commands

It is vital to note that Old Testament instructions for warfare were limited to specific circumstances related to Israel’s possession of the Promised Land or defensive engagements against hostile nations. The commands were neither open-ended nor universal; they were situation-specific to certain groups, often named explicitly (Deuteronomy 7:1–2). When the conquest period concluded, these instructions did not continue as a general mandate. Subsequent warfare narratives in Judges, Samuel, and Kings illustrate that Israel’s own disobedience could result in them experiencing similar judgments.


Sovereign Rights of the Creator

From the Scriptural standpoint, God has sovereignty over life. When He issues critical commands, they rest on His prerogative as Creator and Judge. As Isaiah 45:9 states, “Woe to him who quarrels with his Maker.” The premise is that finite human understanding cannot exhaustively comprehend the full extent of evil or the necessity of divine judgment. Such passages underscore the theological claim that God alone possesses complete knowledge of hearts, motives, and the ripple effects of unbridled wickedness.


Progressive Revelation and Greater Fulfillment

The violent episodes of the Old Testament fit into a broader narrative arc that moves toward Christ’s redemptive work. Early expressions of divine judgment foreshadow the seriousness of sin and the need for atonement. Later, New Testament teachings emphasize the ultimate resolution of sin and violence through Christ’s sacrificial death and victorious resurrection—events that have historical attestation, including documentary evidence from early Christian writings such as the letters of Paul (1 Corinthians 15:3–8) and extrabiblical references from Tacitus and Josephus.

Archaeological and textual studies (e.g., manuscripts of the New Testament in the Chester Beatty Papyri, the Bodmer Papyri, and the thousands of later copies) show remarkable textual consistency, indicating the reliability by which these events have been preserved. This grand storyline transitions from localized judgment in the Old Testament to the universal offer of reconciliation through Christ, a shift that clarifies and further reveals God’s ultimate plan to redeem humanity.


Context of Mercy and Redemption

Despite the harshness of certain Old Testament narratives, there are continual reminders of divine mercy. Rahab, in Joshua 6, receives salvation because of her faith. The Gibeonites, in Joshua 9, are spared once they supplicate for mercy and enter a covenant. These accounts highlight that even within God-commanded judgments, individuals who turn from wickedness and call upon the Lord receive compassion.

Outside Scripture, the historical existence of these people groups is supported by ancient inscriptions referencing the Gibeonites, the Moabites (e.g., the Mesha Stele), and the Hittites (once considered mythological by some until their language and empire were discovered over a century ago). Such historical and archaeological confirmation reinforces the veracity of the Old Testament setting and these narratives of divine justice and mercy.


Resonances in Philosophy and Behavioral Ethics

From a philosophical and behavioral standpoint, the Old Testament’s portrayal of momentarily severe judgment highlights the sober reality of moral accountability. Modern psychological and sociological studies observe that unchecked wrongdoing in communities can spiral into destructive atrocities over generations. The biblical account of God instituting boundaries, culminating in direct intervention, mirrors how ultimate justice can serve as a stark curb on unbridled evil.

At the same time, the message resounds that humanity is not doomed to repeated cycles of destructive behavior; the broader Scriptural canon points to personal transformation and salvation through Christ, offering a path where violence no longer reigns as the final word.


Concluding Perspective

When considering why God commands violence in the Old Testament, several key points emerge: the severe moral depravity of certain nations, the protective purpose of preserving a covenant people who would usher in salvation for the world, and the emphasis that judgment was specific and limited to dire, unrepentant circumstances. Additionally, evidence from archaeology, ancient inscriptions, and the consistent preservation of the biblical manuscripts underscores the historicity of these events and the reliability of the Scriptural narrative.

Ultimately, these Old Testament judgments underscore the seriousness of sin, the necessity of justice, and the reality that God’s desire is to reconcile and restore. The unfolding revelation leads from localized commands of judgment to the universal saving grace achieved through the death and resurrection of Christ—a decisive declaration that God’s mercy triumphs over evil. As Psalm 145:17 affirms, “The LORD is righteous in all His ways and kind in all His deeds,” framing both His justice and mercy as aspects of His sovereign plan.
