Anger Is Murder in the Heart

Matthew 5:21-26 begins the first of six units introduced by some form of "you have heard ... but I say to you." The traditional command "You shall not murder" comes from the Decalogue, but Jesus extends the issue from homicide to anger, insult, and broken relationship. The expression enochos tē krisei means "liable to judgment." A textual complication appears in verse 22: some manuscripts add eikē, "without cause," after "angry with his brother." The shorter reading is generally regarded as earlier because the qualification can be explained as a scribal softening of Jesus' absolute formulation.

The terms raka and mōre are insults, the former likely reflecting Aramaic reqa, approximately "empty-head," and the latter meaning "fool." Jesus' escalating references to local judgment, the council, and "Gehenna of fire" are best read rhetorically rather than as a precise juridical schedule assigning different punishments to different insults. Gehenna derives from the Valley of Hinnom south of Jerusalem and had become an image of eschatological judgment.

Verses 23-26 reinforce the priority of reconciliation through two miniature scenarios: interruption of an offering and settlement with an accuser before reaching court. Debate concerns whether these are literal instructions, hyperbolic examples, or both. Their literary function is clear: the command against murder is interpreted in terms of relationships whose hostility may precede overt violence. Reconciliation therefore belongs to the "greater righteousness" introduced in 5:20.

Matthew 5 opens the Sermon on the Mount, the first of the Gospel's major teaching discourses. Jesus ascends a mountain, sits in the posture of a teacher, and addresses disciples in the presence of the crowds introduced at the end of chapter 4. The chapter moves from the Beatitudes to images of salt and light, then to a programmatic statement about Jesus' relation to the Law and the Prophets. Six subsequent units illustrate the kind of righteousness Jesus demands by treating murder and anger, adultery and desire, divorce, oaths, retaliation, and love of enemies.

The chapter's central interpretive question is how Jesus' teaching relates to Israel's Torah. Matthew explicitly denies that Jesus abolishes the Law and instead speaks of fulfilling it, while the repeated formula "you have heard ... but I say to you" presents Jesus as an authoritative interpreter whose demands reach beyond external conformity to dispositions, intentions, and reconciled relationships. The chapter therefore develops themes introduced earlier in Matthew: kingdom, righteousness, fulfillment, discipleship, and Jesus' distinctive authority.
