This verse in the King James

King James wording
Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother’s righteous.

The same Greek word names both the source of Cain’s violence and the evil quality of his works, making the deed expose what it belongs to.

Cain’s killing is tied to the pattern of his works and to his brother’s alignment. The verse speaks now wherever another person’s goodness feels like an accusation to someone whose own work is bent toward harm. The name Cain carries an “acquire” echo from Genesis 4:1, and here that echo meets an act that takes a brother’s life.

WHAT THIS UNDOES

It undoes the belief that violence can be detached from what is being cultivated: here the killing is explicitly tied to evil work and to the brother’s righteousness.

πονηροῦ

ponērou

GROWS FROM

πονηρ-

evil, harmful, wicked

“from the evil one” in this verse is ponērou. The Greek repeats one word family: Cain is “of the wicked one,” and his works are “evil.” Source and output carry the same verbal stamp, so the violence is shown as a fruit of what it belongs to.

ALSO GROWS

ponēros: wicked, evil

πονηρός

ἔσφαξεν

esphaxen

GROWS FROM

⁨σφαγ-⁩ / ⁨σφαζ-⁩

to slaughter, especially by cutting the throat

“slaughtered” in this verse is esphaxen. The verb depicts slaughter, giving Cain’s act a sharper edge than a general word for death. This same root later describes the Lamb as slain, linking the verse to another image of slaughter.

Romans 8:36 uses this noun in “sheep for the slaughter,” showing the root also names slaughter as a condition faced.

esphagmenon: slaughtered, slain

ἐσφαγμένον

קַיִן

Qayin

GROWS FROM

קנה

q-n-h

acquire, get, possess

Genesis 4:1 links Cain’s name to qanah, “acquire” or “get,” in its naming wordplay. Here that echo meets an act that takes a brother’s life, making the name’s acquisition sound unsettling beside the violence.

ALSO GROWS

qanah: acquire, get, possess

קָנָה

Genesis 4:1 pairs this verb with the naming of Cain in Eve’s words, “I have gotten a man from the LORD.”

qinyan: possession, acquisition

What a person is oriented toward becomes visible in what they produce and do.

And Cain said to Abel his brother. And it came to pass, when they were in the field, that Cain rose up against Abel his brother and killed him.
Genesis 4:8 · SDVCain’s violence makes visible the destructive pattern named in his works.
So every good tree makes good fruit, but the rotten tree makes evil fruit.
Matthew 7:17 · SDVThe tree’s fruit reveals the nature of what is producing it.
Does the same spring gush from the same opening, the sweet and the bitter?
James 3:11 · SDVThe fountain’s output discloses what its source can produce.
And I see in the midst of the throne and of the four living creatures, and in the midst of the older ones, a Lamb standing as though slaughtered, having seven horns and seven eyes, which are the seven breaths of God sent out into all the earth.
Revelation 5:6 · SDV

The Greek verb behind “slew” belongs to the same root as “slain” in Revelation’s image of the Lamb. The shared word brings Cain’s violence and the Lamb’s slaughter into the same lexical light, while leaving their difference visible.
