1The man knew Eve his wife. She conceived, and gave birth to Cain, and said, “I have gotten a man with Yahweh’s help.” 2Again she gave birth, to Cain’s brother Abel. Abel was a keeper of sheep, but Cain was a tiller of the ground. 3As time passed, Cain brought an offering to Yahweh from the fruit of the ground. 4Abel also brought some of the firstborn of his flock and of its fat. Yahweh respected Abel and his offering, 5but he didn’t respect Cain and his offering. Cain was very angry, and the expression on his face fell. 6Yahweh said to Cain, “Why are you angry? Why has the expression of your face fallen? 7If you do well, won’t it be lifted up? If you don’t do well, sin crouches at the door. Its desire is for you, but you are to rule over it.” 8Cain said to Abel, his brother, “Let’s go into the field.” While they were in the field, Cain rose up against Abel, his brother, and killed him.
9Yahweh said to Cain, “Where is Abel, your brother?”
He said, “I don’t know. Am I my brother’s keeper?”
10Yahweh said, “What have you done? The voice of your brother’s blood cries to me from the ground. 11Now you are cursed because of the ground, which has opened its mouth to receive your brother’s blood from your hand. 12From now on, when you till the ground, it won’t yield its strength to you. You will be a fugitive and a wanderer in the earth.”
13Cain said to Yahweh, “My punishment is greater than I can bear. 14Behold, you have driven me out today from the surface of the ground. I will be hidden from your face, and I will be a fugitive and a wanderer in the earth. Whoever finds me will kill me.”
15Yahweh said to him, “Therefore whoever slays Cain, vengeance will be taken on him sevenfold.” Yahweh appointed a sign for Cain, so that anyone finding him would not strike him.
16Cain left Yahweh’s presence, and lived in the land of Nod, east of Eden. 17Cain knew his wife. She conceived, and gave birth to Enoch. He built a city, and named the city after the name of his son, Enoch. 18Irad was born to Enoch. Irad became the father of Mehujael. Mehujael became the father of Methushael. Methushael became the father of Lamech. 19Lamech took two wives: the name of the first one was Adah, and the name of the second one was Zillah. 20Adah gave birth to Jabal, who was the father of those who dwell in tents and have livestock. 21His brother’s name was Jubal, who was the father of all who handle the harp and pipe. 22Zillah also gave birth to Tubal Cain, the forger of every cutting instrument of bronze and iron. Tubal Cain’s sister was Naamah. 23Lamech said to his wives,
“Adah and Zillah, hear my voice.
You wives of Lamech, listen to my speech,
for I have slain a man for wounding me,
a young man for bruising me.
24If Cain will be avenged seven times,
truly Lamech seventy-seven times.”
25Adam knew his wife again. She gave birth to a son, and named him Seth, saying, “for God has given me another child instead of Abel, for Cain killed him.” 26A son was also born to Seth, and he named him Enosh. At that time men began to call on Yahweh’s name.
Cain was the first son of Adam and Eve, as well as the brother of Abel. The two brothers offered sacrifices to God, but Abel's animal sacrifice was deemed acceptable, whereas Cain's offering of produce was not. This gave rise to Cain murdering his brother, Abel. We have acquired the statement that Cain made to God after He had challenged Cain regarding this conflict between the brothers, in which Cain said, "Am I my brother's keeper." Due to his sin of murdering Abel, Cain was marked by God and became a vagabond in the earth. When Cain responded to God's punishment of banishment, he responded that this was too great a punishment and that he would be killed by others. In response, God marked him and said that anyone who killed Cain would receive sevenfold the punishment should they do so. The Bible indicates that he traveled in his exile to the land of Nod, which is east of the Garden of Eden.
