Genesis 4

1. Now Adam knew Eve his wife, and she conceived and bore Cain, and said, "I have gotten a man from the Lord."
2. Then she bore again, this time his brother Abel.  Now Abel was a keeper of sheep, but Cain was a tiller of the ground.
3. And in the process of time it came to pass that Cain brought an offering of the fruit of the ground to the Lord.  (Num. 18:12)
4. Abel also brought of the firstlings of his flock and of their fat.  And the Lord respected Abel and his offering,  (Num. 18:17)
5. but He did not respect Cain and his offering.  And Cain was very angry, and his countenance fell.  (Heb. 11:4)
6. So the Lord said to Cain, "Why are you angry?  And why has your countenance fallen?
   
7. "If you do well, will you not be accepted?  And if you do not do well, sin lies at the door.  And its desire is for you, but you should rule over it."
   
14. "Surely You have driven me out this day from the face of the ground; I shall be hidden from Your face; I shall be a fugitive and a vagabond on the earth, and it will happen that anyone who finds me will kill me."  (Isaiah 1:15)
15. And the Lord said to him, "Therefore, whoever kills Cain, vengeance shall be taken on him sevenfold."  And the Lord set a mark on Cain, lest anyone finding him should kill him.  (Psalm 79:12;   Ezekiel 9:4-6)
16. Then Cain went out from the presence of the Lord and dwelt in the land of Nod on the east of Eden.  (Jon. 1:3)
17. And Cain knew his wife, and she conceived and bore Enoch.  And he built a city, and called the name of the city after the name of his son - - Enoch  (Psalm 49:11)
