GENESIS 4
Cain and Abel
About This Chapter
After Adam and Eve are driven from the Garden of Eden, the biblical story turns to their children. Genesis 4 reveals how sin begins affecting relationships within the first human family, leading to jealousy, violence, and the first recorded murder.
As you read, notice that God warns Cain before he acts, giving him an opportunity to resist the anger growing within him. Cain's response to that warning, and his actions afterward, reveal how destructive sin can become when it is allowed to take control.
The chapter also follows Cain's descendants and shows the beginnings of human civilization, including the development of cities, music, and metalworking. Yet alongside these achievements, violence continues to grow. By the end of the chapter, the account returns to Adam and Eve's family through Seth, whose descendants will become important in the chapters that follow.
1Adam slept with his wife Eve, and she became pregnant and gave birth to Cain. She said, "With the LORD's help I have brought a man into the world." 2Later she gave birth to his brother Abel.
Abel became a shepherd, and Cain became a farmer.
3When harvest time came, Cain brought some of his crops as an offering to the LORD. 4Abel also brought an offering. He brought fat portions from some of the firstborn lambs of his flock. The LORD was pleased with Abel and his offering, 5but he was not pleased with Cain and his offering. So Cain became very angry, and his face showed it.
What This Means | Why Was Abel's Offering Accepted? Scripture tells us that God accepted Abel's offering but did not accept Cain's. However, Genesis does not explicitly explain every reason for this distinction. Hebrews 11:4 tells us that Abel offered his sacrifice through faith, while 1 John 3:12 describes Cain's actions as evil and his brother's as righteous. Together, these passages show that the difference involved more than simply what each brother brought. Their faith and actions mattered.
6Then the LORD said to Cain, "Why are you so angry? Why is your face so gloomy? 7If you do what is right, won't you be accepted? But if you don't do what is right, sin is crouching at your door like an animal waiting to pounce. Its desire is to control you, but you must master it."
8Cain said to his brother Abel, "Let's go out to the field." And while they were in the field, Cain attacked his brother Abel and killed him.
9Then the LORD said to Cain, "Where is your brother Abel?"
"I don't know," he answered. "Am I supposed to keep track of my brother?"
10The LORD said, "What have you done? Listen! Your brother's blood is crying out to me from the ground. 11Now you are under a curse, and you are driven away from the ground, which opened its mouth to receive your brother's blood from your hand. 12When you work the ground, it will no longer give you its crops. You will be a restless wanderer on the earth."
13Cain said to the LORD, "My punishment is more than I can bear. 14Today you are driving me off the land, and I will be hidden from your presence. I will be a restless wanderer on the earth, and anyone who finds me will kill me."
15But the LORD said to him, "No. Anyone who kills you will be paid back seven times over." Then the LORD put a mark on Cain so that no one who found him would kill him. 16So Cain went away from the LORD's presence and lived in the land of Nod, east of Eden.
Cain's Family
17Cain slept with his wife, and she became pregnant and gave birth to Enoch. Cain was building a city at the time, and he named it Enoch after his son. 18Enoch had a son named Irad. Irad was the father of Mehujael, Mehujael was the father of Methushael, and Methushael was the father of Lamech.
What This Means | Where Did Cain's Wife Come From? Genesis does not identify Cain's wife or explain exactly where she came from. However, Genesis 5:4 tells us that Adam and Eve had other sons and daughters. This has led to the traditional explanation that Cain married a sister or another close relative. While this is a reasonable possibility within the Genesis account, Scripture does not explicitly confirm it. Some have suggested that close-relative marriages would not have presented the same genetic risks early in human history because harmful genetic mutations had not yet accumulated. This remains speculation, since Scripture does not describe the genetic condition of the first humans. Much later, the Law of Moses specifically prohibited sexual relationships between close relatives in Leviticus 18.
19Lamech married two women. One was named Adah and the other Zillah. 20Adah gave birth to Jabal. He was the ancestor of those who live in tents and raise livestock. 21His brother's name was Jubal. He was the ancestor of all who play the harp and the flute. 22Zillah also had a son, Tubal-Cain, who made all kinds of tools out of bronze and iron. Tubal-Cain's sister was Naamah.
23Lamech said to his wives,
"Adah and Zillah, listen to me.
Wives of Lamech, hear what I say.
I have killed a man for wounding me,
a young man for hitting me.
24If Cain is avenged seven times,
then Lamech will be avenged seventy-seven times."
What This Means | From Vengeance to Forgiveness Lamech boasts that his revenge will be far greater than Cain's, claiming vengeance seventy-seven times over. His words reveal how violence has continued to grow among Cain's descendants. Jesus later uses the same number in Matthew 18:21–22 when teaching Peter about forgiveness. Where Lamech speaks of multiplying revenge, Jesus teaches His followers to extend forgiveness without keeping count.
Seth and Enosh
25Adam slept with his wife again, and she gave birth to a son. She named him Seth, saying, "God has given me another child in place of Abel, since Cain killed him." 26Seth also had a son, and he named him Enosh.
At that time people began to call on the name of the LORD.
