STRONGS NT 2535: Κάϊν

Κάϊν (WH Κάϊν (cf. Ἰ´, at the end)), , indeclinable (in Josephus with a Greek ending, Καις, Καιτος; Hebrew קַיִן i. e. a spear, although the author of Genesis, , derives it from קָנָה to produce, beget, acquire, so that it is equivalent to קִנְיָן, Psalm 104:24 (cf. B. D. American edition under the word)), Cain, the fratricide, the first-born son of Adam: Hebrews 11:4; 1 John 3:12; Jude 1:11.

Topical Lexicon
Identity and Setting

Kain (Cain) is the first child born to the human race (Genesis 4:1), the elder brother of Abel, and a tiller of the ground. His name is preserved in the Greek New Testament as Καίν (Strong’s 2535).

Early Worship and Sacrifice

Cain and Abel present Scripture’s earliest record of formal offerings (Genesis 4:3–4). Abel’s blood sacrifice was accepted, Cain’s produce offering was rejected. The text links acceptance to the heart of the worshiper rather than to the material of the sacrifice alone (cf. Hebrews 11:4). Thus Cain becomes the archetype of worship without faith, illustrating that outward form cannot substitute for inward trust and obedience.

Sin, Jealousy, and Fratricide

When Cain’s countenance fell, the LORD warned, “Sin is crouching at the door; its desire is for you, but you must master it” (Genesis 4:7). Cain rejected the admonition, murdered Abel, and then denied responsibility: “Am I my brother’s keeper?” (Genesis 4:9). His act reveals the rapid spread of depravity after the Fall, showing how envy can mature into violence once sin is tolerated.

Divine Judgment and Mercy

Cain is cursed from the ground, becomes a restless wanderer, and settles “east of Eden” in the land of Nod (Genesis 4:11–16). Yet the LORD places a mark of protection on him, demonstrating both justice and mercy. Cain’s line later develops city life, arts, and technology (Genesis 4:17–22), underscoring that cultural advance can coexist with spiritual alienation.

New Testament Usage of Kain (Strong’s 2535)

1. Hebrews 11:4 contrasts the brothers: “By faith Abel offered God a better sacrifice than Cain did…”. Cain embodies religion devoid of faith; Abel, faith that gains divine approval.
2. 1 John 3:12 cautions believers: “Do not be like Cain, who belonged to the evil one and murdered his brother…”. Cain typifies hatred that springs from unrighteous deeds and exposes one’s spiritual parentage.
3. Jude 11 groups false teachers with notorious rebels: “They have traveled the way of Cain…”. Here “the way of Cain” denotes self-willed, profit-seeking religion that spawns violence and judgment.

Doctrinal Themes

• Faith versus works: Cain’s offering arises from human effort, Abel’s from faith, prefiguring the contrast between self-righteousness and justification by faith.
• Brotherly responsibility: Cain’s denial highlights the moral imperative to love one’s neighbor (Leviticus 19:18; Matthew 22:39).
• Bloodshed and atonement: Abel’s blood “still speaks” (Hebrews 12:24), yet Jesus’ blood “speaks a better word,” providing the final answer to the violence Cain introduced.

Christological Contrast

Hebrews 12:24 sets “the sprinkled blood” of Christ against Abel’s. Abel’s blood cries for justice; Christ’s blood secures mercy. Thus the tragedy of Cain foreshadows the triumph of the cross, where divine justice and grace meet perfectly.

Practical Ministry Applications

• Examine worship motives: outward gifts cannot mask unbelief.
• Guard the heart against envy; unchecked resentment births destructive actions and ministries.
• Teach accountability: believers are their brothers’ keepers, called to proactive love.
• Warn against “the way of Cain”: self-made religion that resists correction and seeks gain will end in judgment (Jude 11).

Jewish and Early Christian Reflection

Second-Temple literature (e.g., Wisdom of Solomon 10:3) and early church fathers (e.g., Clement of Rome, Tertullian) consistently used Cain as a negative paradigm. His figure reinforced the call to brotherly love and highlighted the peril of jealousy within the covenant community.

Summary

Kain stands as Scripture’s first example of worship divorced from faith, a warning against envy, violence, and self-righteous religion. The New Testament employs his name to expose false teachers and unloving behavior, directing believers instead to the faith of Abel and, ultimately, to the redemptive blood of Jesus Christ that overcomes the legacy of Cain.
