In the biblical context, capital punishment by the sword is a form of execution that is mentioned as a means of enacting divine justice and maintaining societal order. The use of the sword as an instrument of capital punishment is depicted in various passages throughout the Scriptures, reflecting the seriousness with which certain transgressions were regarded in ancient Israelite society.

Old Testament Context

The Old Testament provides several instances where the sword is used as a means of executing divine judgment. In Leviticus 26:25, God warns the Israelites of the consequences of disobedience, stating, "And I will bring a sword against you to execute the vengeance of the covenant." Here, the sword symbolizes divine retribution against covenant unfaithfulness.

In the historical narratives, the sword is often employed in the context of warfare and judgment against nations. For example, in 1 Samuel 15:33, the prophet Samuel executes Agag, the king of the Amalekites, with the sword, saying, "As your sword has made women childless, so your mother will be childless among women." This act is portrayed as a fulfillment of God's command to utterly destroy the Amalekites for their opposition to Israel.

The sword is also mentioned in the context of individual transgressions. In Numbers 25:7-8, Phinehas, the grandson of Aaron, uses a spear (a form of sword) to execute an Israelite man and a Midianite woman who were flagrantly violating God's commandments, thus halting a plague among the Israelites. This act of zeal is commended by God and is seen as an act of righteous judgment.

New Testament Context

In the New Testament, the sword continues to be a symbol of authority and judgment. Romans 13:4 speaks to the role of governing authorities as agents of God's justice: "For he is God’s servant for your good. But if you do wrong, be afraid, for he does not carry the sword in vain. He is God’s servant, an agent of retribution to bring punishment on the wrongdoer." Here, the sword represents the legitimate power of the state to enforce justice, including capital punishment.

The Book of Revelation also uses the imagery of the sword to depict divine judgment. In Revelation 19:15, Christ is described as wielding a sharp sword to strike down the nations: "From His mouth proceeds a sharp sword with which to strike down the nations, and He will rule them with an iron scepter." This apocalyptic imagery underscores the ultimate authority of Christ in executing divine justice.

Theological Implications

The use of the sword as a means of capital punishment in the Bible underscores the gravity of sin and the necessity of justice. It reflects the biblical principle that certain actions, particularly those that threaten the covenant community or defy divine authority, warrant the most severe consequences. The sword, as an instrument of execution, serves as a deterrent against lawlessness and a means of purging evil from among God's people.

While the New Testament emphasizes mercy and forgiveness, it does not negate the role of justice and the authority of the state to wield the sword in maintaining order. The biblical portrayal of capital punishment by the sword thus reflects a balance between justice and mercy, underscoring the holiness of God and the seriousness of sin.1 Samuel 15:33
And Samuel said, As the sword has made women childless, so shall your mother be childless among women. And Samuel hewed Agag in pieces before the LORD in Gilgal.
