Genesis 4:3-5

— Key verse about Cain

Who Was Cain?

Cain was the firstborn son of Adam and Eve and a tiller of the ground. When God accepted Abel's offering but not his, Cain's jealousy and anger led him to murder his brother — the first murder in human history. God judged Cain but also placed a mark of protection upon him, showing that even severe sin does not place a person entirely beyond God's care.

Cain appears in: Genesis , Hebrews , 1 John , Jude

Frequently Asked Questions

Why did God reject Cain's offering?

Scripture does not give a single explicit reason. Hebrews 11:4 says Abel offered "by faith" a more excellent sacrifice than Cain. Some scholars note that Abel brought the firstlings and the fat portions (his best), suggesting Cain's offering lacked faith or devotion. God's response to Cain (Genesis 4:7) implies Cain knew what was expected but chose otherwise.

What was the mark of Cain?

Genesis 4:15 says God set a mark upon Cain so that anyone finding him would not kill him. The nature of this mark is not described in Scripture. It was a sign of God's protective mercy, not a curse. Speculation about what the mark was has varied widely but remains uncertain.

Who did Cain marry?

Genesis 4:17 states that Cain had a wife, but does not name her. Since Adam and Eve had many sons and daughters (Genesis 5:4), Cain would have married a sister or close relative. In the earliest generations of humanity, this was necessary and not prohibited until the Law of Moses.
