Enemy
Scripture treats "enemy" as a layered category. There are enemies of Yahweh who set themselves against him and his people; there are foreign armies who threaten Israel in war; there are personal adversaries — the lying witness, the false friend, the kinsman who turns; and there is a final enemy that outlasts the others. The Old Testament cries for vengeance against the wicked sit alongside laws and proverbs commanding kindness toward the man who hates you. Jesus then folds the personal enemy and the persecutor into a single command — love them, do good to them, pray for them — and Paul quotes Pr 25:21 verbatim to ground that ethic in older Hebrew wisdom.
Enemies of Yahweh
The earliest songs of Israel celebrate Yahweh as a warrior who shatters his adversaries. After the Sea: "Your right hand, O Yahweh, is glorious in power, Your right hand, O Yahweh, dashes in pieces the enemy" (Ex 15:6). The Song of Moses promises the same recompense to those who hate him: "I will render vengeance to my adversaries, And will recompense those who hate me" (De 32:41). Deborah's song closes with the prayer that becomes a formula: "So let all your enemies perish, O Yahweh: But let those who love him be as the sun when he goes forth in his might" (Jg 5:31).
The same idiom carries through the Psalter and the prophets. "Let God arise, let his enemies be scattered; And let those who hate him flee before him" (Ps 68:1). Isaiah hears Yahweh declare, "I will ease myself of my adversaries, and avenge myself of my enemies" (Is 1:24); the foreigner who plunders Israel's grain will not drink her wine (Is 62:8). The category is moral as much as national — those who rise against Yahweh and those who oppress his people are spoken of together (Ps 74:23).
Enemies in War
Israel's narrative books treat external armies as the standing pressure under which the nation lives. Yahweh "delivered you⁺ out of the hand of your⁺ enemies on every side; and you⁺ dwelt in safety" (1Sa 12:11). The return from exile is told the same way: "the hand of our God was on us, and he delivered us from the hand of the enemy and the ambusher by the way" (Ezr 8:31).
First Maccabees gives the longest sustained vocabulary for the war-enemy. Mattathias laments the city "given into the hands of the enemies" (1Ma 2:7). Apollonius gathers nations from Samaria "to make war against Israel" (1Ma 3:10), and Judas describes them as coming "with a multitude of insult, and of lawlessness, to destroy us, and our wives, and our children, and to take our spoils" (1Ma 3:20). The prayer before Beth-horon — "Shut up this army in the hands of your people Israel, And let them be confounded in their host and their horsemen" (1Ma 4:31) — fuses the war cry with the imprecatory psalm. Late in the book Simon's sons receive the same inheritance: their family "have fought against the enemies of Israel from our youth even to this day" (1Ma 16:2; cf. 1Ma 14:29, 14:31).
Personal Enemies
Beyond armies, the Wisdom and Sirach material treat the enemy as a feature of ordinary social life. "There is a friend who turns into an enemy, And with strife he will uncover your reproach" (Sir 6:9). "Never trust in an enemy; For like bronze, his evil will corrode" (Sir 12:10). Sirach also recognises the bitterness of the calamity that comes from haters specifically: "Any calamity, only not the calamity of haters! Any vengeance, only not the vengeance of enemies!" (Sir 25:14).
The Davidic psalms voice the same experience from inside a sufferer's mouth. "Unrighteous witnesses rise up; They ask me of things that I don't know" (Ps 35:11). "Those who hate me without a cause are more than the hairs of my head: Those who would cut me off, being my enemies wrongfully, are mighty" (Ps 69:4). The personal enemy in this register is not a foreign army; it is the slanderer, the false witness, the one who hates without cause.
The Imprecatory Psalms
Out of that situation come the prayers for harm against the enemy that Scripture calls down by name. "Break the arm of the wicked; And as for the evil man, seek out his wickedness until you find none" (Ps 10:15). "Let death come suddenly on them, Let them go down alive into Sheol" (Ps 55:15). "Break their teeth, O God, in their mouth: Break out the great teeth of the young lions, O Yahweh" (Ps 58:6). "As smoke is driven away, you will drive them away: As wax melts before the fire, So let the wicked perish at the presence of God" (Ps 68:2).
The most pointed are Ps 69 and Ps 109. "Let their table before them become a snare; And for the secure ones, [let it become] a trap" (Ps 69:22). "Set a wicked man over him; And let an adversary stand at his right hand" (Ps 109:6). The exilic Ps 137 turns toward Edom: "Remember, O Yahweh, against the sons of Edom The day of Jerusalem; Who said, Raze it, raze it, Even to its foundation" (Ps 137:7).
The same mode shows up outside the Psalter when a covenant offence is in view. Nehemiah prays against the mockers of the wall-builders: "don't cover their iniquity, and don't let their sin be blotted out from before you" (Ne 4:5). Elijah calls down fire on the captain of fifty (2Ki 1:10). Judas Maccabeus prays against Nicanor in the same idiom: "Be avenged of this man, and his army, and let them fall by the sword: remember their blasphemies, and do not give them a dwelling place" (1Ma 7:38). Paul's "let him be accursed" against those who preach a false gospel (Ga 1:9) belongs to this same vocabulary, transposed into church discipline.
Kindness to the Enemy
Alongside that vocabulary the same canon places a counter-tradition. The Covenant Code already legislates toward the personal enemy: "If you see the donkey of him who hates you lying under his burden, you will forbear to leave him, you will strengthen [it] with him" (Ex 23:5). Job will not allow himself even private satisfaction at his hater's ruin: "If I have rejoiced at the destruction of him who hated me, Or lifted up myself when evil found him … (Yes, I haven't allowed my mouth to sin By asking for his soul with a curse)" (Job 31:29-30).
Proverbs frames the same posture as wisdom. "Don't rejoice when your enemy falls, And don't let your heart be glad when he is overthrown; Or else Yahweh will see it, and it will be evil in his eyes, And he will turn away his wrath from him" (Pr 24:17-18). And the line Paul will quote in Romans: "If your enemy is hungry, give him bread to eat; And if he is thirsty, give him water to drink: For you will heap coals of fire on his head, And Yahweh will reward you" (Pr 25:21-22).
Old-Covenant Forgiveness Narratives
The narrative books supply concrete examples. Joseph, after Jacob dies and his brothers come fearing reprisal, refuses the role: "Don't be afraid: for am I in the place of God? And as for you⁺, you⁺ meant evil against me; but [the Speech of] God meant it for good, to bring to pass, as it is this day, to save many people alive. Now therefore don't be⁺ afraid: I will nourish you⁺, and your⁺ little ones. And he comforted them, and spoke kindly to them" (Ge 50:19-21).
David twice spares Saul when Saul is hunting him. In the cave: "Yahweh forbid that I should put forth my hand against Yahweh's anointed: but now take, I pray you, the spear that is at his head, and the cruse of water, and let us go" (1Sa 26:11). Saul's response gives the principle a name: "You are more righteous than I; for you have rendered to me good, whereas I have rendered to you evil" (1Sa 24:17). Later, after Absalom's revolt, Joab rebukes David for the inverse problem — mourning the rebel son so heavily that he insults the soldiers who saved him: "in that you love those who hate you, and hate those who love you" (2Sa 19:6). David responds by extending amnesty to Amasa, who had captained Absalom's army: "You⁺ are my brothers, you⁺ are my bone and my flesh. Why then are you⁺ the last to bring back the king?" (2Sa 19:12) — and "And say⁺ to Amasa, Are you not my bone and my flesh? God do so to me, and more also, if you are not captain of the host before me continually in the place of Joab" (2Sa 19:13).
Elisha, asked whether to strike a captured Aramean force, gives the same answer: "You will not strike them: would you strike those whom you have taken captive with your sword and with your bow? Set bread and water before them, that they may eat and drink, and go to their master" (2Ki 6:22). Even David's complaint psalm preserves the practice: "But as for me, when they were sick, my clothing was sackcloth: I afflicted my soul with fasting" (Ps 35:13).
"Love your⁺ enemies"
Luke 6 collects the New Testament version of the kindness tradition. "But I say to you⁺ who hear, Love your⁺ enemies, do good to those who hate you⁺, bless those who curse you⁺, pray for those who despitefully use you⁺. To him who strikes you on the [one] cheek offer also the other; and from him who takes away your cloak don't withhold your coat also. Give to everyone who asks you; and of him who takes away your goods don't ask [for them] back. And as you⁺ would that men should do to you⁺, do⁺ to them likewise" (Lu 6:27-31).
The argument is then framed as a cost-of-discipleship calculation: "if you⁺ love those who love you⁺, what thanks do you⁺ have? For even sinners love those who love them. For even if you⁺ do good to those who do good to you⁺, what thanks do you⁺ have? Even sinners do the same. And if you⁺ lend to them of whom you⁺ hope to receive, what thanks is it to you⁺? Even sinners lend to sinners, to receive again as much" (Lu 6:32-34). The saying closes by tying the practice to the Father's character: "love your⁺ enemies, and do [them] good, and lend, never despairing; and your⁺ reward will be great, and you⁺ will be sons of the Most High: for he is kind toward the unthankful and evil. Be⁺ merciful, even as your⁺ Father is merciful" (Lu 6:35-36).
The healing of the high priest's slave in Gethsemane gives the teaching a narrative example: "But Jesus answered and said, Allow⁺ [them] thus far. And he touched his ear, and healed him" (Lu 22:51).
Paul and the Apostolic Echo
Paul folds the same Hebrew material into Romans 12 without altering it. "Bless those who persecute you⁺; bless, and do not curse" (Ro 12:14). "But if your enemy hungers, feed him; if he thirsts, give him to drink: for in so doing you will heap coals of fire on his head" (Ro 12:20) — a direct quotation of Pr 25:21. First Thessalonians turns the same posture into a community rule: "See that none render to anyone evil for evil; but always follow after that which is good, both one toward another, and toward all" (1Th 5:15). Paul adduces his own conduct as evidence: "being reviled, we bless; being persecuted, we endure" (1Co 4:12).
The second-century Epistle to the Greeks preserves the same shape, now read as a description of Christian existence in the world. Christians "are reviled, and bless; they are shamefully treated, and render honor" (Gr 5:15); "they are warred against as aliens, and by the Greeks they are persecuted; and those who hate them can give no reason of their enmity" (Gr 5:17); and "Christians love those who hate them" (Gr 6:6).
The Last Enemy
The categories of enemy converge in one final entry. After cataloguing the resurrection, Paul names the residual hostility that outlasts every other combatant: "The last enemy that will be abolished is death" (1Co 15:26). The vocabulary that began with Pharaoh's chariots dashed in pieces (Ex 15:6) ends with death itself listed as the final adversary marked for defeat.
