1 Adam lay with his wife Eve and she gave birth to Cain, and she said, “I have created a man with the help of the Lord !” 2 She also gave birth to his brother Abel. Abel was a shepherd, but Cain was a farmer.
3 In the course of time Cain brought some of the produce of the ground as an offering to the Lord . 4 Abel too brought some of the choicest animals of his flock and sacrificed their fat pieces. The Lord looked with approval on Abel and his offering 5 but he could not receive Cain and his offering with approval.
Therefore Cain was very angry and his face fell. 6 So the Lord said to Cain, “Why are you angry and why do you scowl? 7 If you do what is right and good, will not your offering be accepted? But if you do wrong, sin crouches at the door and the inclination to sin will overcome you, but you should master it.”
8 Cain said to his brother Abel, “Let us go into the field.” While they were in the field, Cain attacked his brother and killed him.
9 Then the Lord said to Cain, “Where is your brother Abel?” He answered, “I do not know; am I my brother's keeper?” 10 The Lord said, “What have you done? Listen! Your brother's blood is crying to me from the ground. 11 Even now you are cursed by the very ground that has opened to receive your brother's blood from your hand. 12 Whenever you till the ground, it will no longer yield to you its strength; you will be a vagabond and a wanderer on the earth.”
13 Then Cain said to the Lord , “My punishment is more than I can bear. 14 See, you have driven me out today from this land, and I will no longer be able to worship you; I shall become a vagabond and a wanderer on the earth, and whoever finds me will kill me.”
15 But the Lord said to him, “If any one kills you, the crime shall be avenged sevenfold.” So the Lord placed a tribal mark on Cain, to keep any one who found him from killing him. 16 Cain departed from the Lord 's presence and lived east of Eden in the land of Wandering.
17 Cain lay with his wife; and she conceived, and bore Enoch. Cain built a city, and named the city after his son Enoch. 18 To Enoch was born Irad; and Irad fathered Mehujael; and Mehujael fathered Methushael; and Methushael fathered Lamech.
25 Adam lay with his wife again; and she bore a son, and named him Seth: “because God gave me another son for Abel, who was killed by Cain.” 26 Seth too had a son; he named him Enosh. That was when people began using the name of Lord in worship.
