Cain and Abel
(Romans 2:1-16; Jude 1:3-16)
1And Adam had relations with  his wife Eve, and she conceived and gave birth to  Cain. “With the help of the LORD I have brought forth a man,” she said. 
2Later she gave birth  to Cain’s brother  Abel. Now Abel was a keeper of sheep, while Cain was a tiller of the soil. 
3So in the course of time,  Cain brought some of the fruit of the soil as an offering to the LORD, 
4while Abel   brought the best portions of the firstborn of his flock. And the LORD looked with favor on Abel and his offering, 
5but He had no regard for Cain and his offering. So Cain became very angry, and his countenance fell. 
6“Why are you angry,” said the LORD to Cain, “ and why has your countenance fallen? 
7If you do what is right, will you not be accepted? But if you refuse to do what is right, sin is crouching at your door; it desires you, but you must master it.”
Cain Murders Abel
8Then Cain said to his brother Abel, “Let us go out to the field.” And while they were in the field, Cain rose up against his brother Abel and killed him.
9And the LORD said to Cain, “Where is your brother Abel?” “I do not know!” he answered. “Am I my brother’s keeper?” 
10“What have you done?” replied the LORD. “The voice of your brother’s blood cries out to Me from the ground. 
11Now you are cursed and banished from the ground, which has opened  its mouth to receive  your brother’s blood from your hand. 
12When you till  the ground, it will no longer yield its produce to you. You will be a fugitive and a wanderer on the earth.” 
13But Cain said to the LORD, “My punishment is greater than I can bear. 
14Behold, this day You have driven me from the face of the earth, and from Your face I will be hidden; I will be a fugitive and a wanderer on the earth, and whoever finds me will kill me.” 
15“Not so!” replied the LORD.  “If anyone slays Cain, then Cain will be avenged sevenfold.” And the LORD placed a mark on Cain, so that no one  who found him would kill him.
16So Cain went out from the presence of the LORD and settled in the land of Nod, east of Eden.
The Descendants of Cain
17And Cain  had relations with his wife, and she conceived and gave birth to  Enoch. Then Cain built a city and named  it after his son Enoch. 
18Now to Enoch  was born Irad, and Irad was the father of  Mehujael, and Mehujael was the father of  Methusael, and Methusael was the father of  Lamech. 
19And Lamech married  two women, one named Adah and the other Zillah. 
20Adah  gave birth to Jabal; he was the father of those who dwell in tents and raise livestock. 
21And his brother’s name was Jubal; he was the father of all who play the harp and flute. 
22And Zillah   gave birth to   Tubal-cain, a forger of every implement of bronze and iron. And the sister  of Tubal-cain was Naamah.
23Then Lamech said to his wives: “Adah and Zillah, hear my voice; wives of Lamech, listen to my speech. For I have slain a man for wounding me, a young man for striking me.
24If Cain is avenged sevenfold, then Lamech  seventy-sevenfold.”
Seth and Enosh
25And Adam again had relations with his wife,  and she gave birth to a son and named  him Seth, saying, “God has granted me another seed in place of Abel, since Cain killed him.” 
26And to Seth  also a son was born, and he called  him Enosh. At that time men began to call upon the name of the LORD.
