Cain and Abel. 1The man had relations with his wife Eve, and she conceived and bore Cain, saying, “I have produced a man with the help of the LORD.”* 2Next she bore his brother Abel. Abel became a keeper of flocks, and Cain a tiller of the soil. 3In the course of time Cain brought an offering to the LORD from the fruit of the soil, 4while Abel, for his part, brought one of the best firstlings of his flock. n Ex 34, 19; Heb 11, 4 . The LORD looked with favor on Abel and his offering, 5but on Cain and his offering he did not. Cain greatly resented this and was crestfallen. 6So the LORD said to Cain: “Why are you so resentful and crestfallen? 7If you do well, you can hold up your head; but if not, sin is a demon lurking* at the door: his urge is toward you, yet you can be his master.” o Sir 7, 1; Jude11.
8Cain said to his brother Abel, “Let us go out in the field.” When they were in the field, Cain attacked his brother Abel and killed him. p Wis 10, 3; Mt 23, 35; Lk 11, 51; 1 Jn 3, 12; Jude 11. 9Then the LORD asked Cain, “Where is your brother Abel?” He answered, “I do not know. Am I my brother's keeper?” 10The LORD then said: “What have you done! Listen: Your brother's blood cries out to me from the soil! 11Therefore you shall be banned from the soil that opened its mouth to receive your brother's blood from your hand. q Dt 27, 24 . 12If you till the soil, it shall no longer give you its produce. You shall become a restless wanderer on the earth.” 13Cain said to the LORD: “My punishment is too great to bear. 14Since you have now banished me from the soil, and I must avoid your presence and become a restless wanderer on the earth, anyone may kill me at sight.” 15“Not so!” the LORD said to him. “If anyone kills Cain, Cain shall be avenged sevenfold.” So the LORD put a mark* on Cain, lest anyone should kill him at sight. 16Cain then left the LORD's presence and settled in the land of Nod,* east of Eden.
Descendants of Cain and Seth. 17 *Cain had relations with his wife, and she conceived and bore Enoch. Cain also became the founder of a city, which he named after his son Enoch. 18To Enoch was born Irad, and Irad became the father of Mehujael; Mehujael became the father of Methusael, and Methusael became the father of Lamech. 19Lamech took two wives; the name of the first was Adah, and the name of the second Zillah. 20Adah gave birth to Jabal, the ancestor of all who dwell in tents and keep cattle. 21His brother's name was Jubal; he was the ancestor of all who play the lyre and the pipe. 22Zillah, on her part, gave birth to Tubalcain, the ancestor of all who forge instruments of bronze and iron. The sister of Tubalcain was Naamah. 23Lamech said to his wives:
“Adah and Zillah, hear my voice; wives of Lamech, listen to my utterance: I have killed a man for wounding me, a boy for bruising me. 24If Cain is avenged sevenfold, then Lamech seventy‐sevenfold.”
25Adam again had relations with his wife, and she gave birth to a son whom she called Seth. “God has granted* me more offspring in place of Abel,” she said, “because Cain slew him.” 26To Seth, in turn, a son was born, and he named him Enosh.
At that time men began to invoke the LORD by name. r 1 Chr 1, 1; Lk 3, 38 .
