    Quick Answer

    Cain was the firstborn son of Adam and Eve who murdered his brother Abel and became the archetype of unrepentant sin in Scripture.

    "And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him." Genesis 4:8 (KJV)

    The Biblical Context

    Cain occupies a tragic place in biblical history as the first human born and the first murderer. When Adam and Eve had two sons, Cain became a tiller of the ground while Abel was a keeper of sheep. Both brothers brought offerings to the Lord, but God respected Abel and his offering while rejecting Cain's. The difference was not in the type of offering but in the heart behind it — Hebrews 11:4 tells us Abel offered by faith, while Cain's offering lacked true devotion. Rather than repenting, Cain became angry, and God warned him that sin was crouching at his door. Cain lured Abel into the field and killed him, then callously asked, 'Am I my brother's keeper?' God pronounced a curse upon Cain, making him a fugitive and vagabond upon the earth. Though Cain complained that his punishment was unbearable, God mercifully set a mark upon him to prevent his being killed. Cain went to the land of Nod and built a city, naming it after his son Enoch. His descendants are noted for their advancement in worldly arts and culture, yet also for increasing violence. Cain's story illustrates the progressive nature of sin — from jealousy to anger to murder — and the necessity of offering God our best with a right heart.
