Adam named his wife Eve, because she was the mother of all living beings. She had two sons, cain and Abel. Abel was a shepherd, but Cain was a farmer.
One day Cain brought, as an offering to the LORD, some fruit and grain that he had grown. Abel, too, brought some of the best animals of his flock and sacrificed their fat pieces to the LORD. the LORD was pleased with Abel and his offering, but Cain and his offering did not please him.
This made Cain very angry and his face showed it. So the LORD said to Cain, "Why are you angry and why do you scowl? If you do what is right and good, will not your offering be accepted? But if you do wrong, sin crouches like a wild beast at the door and the desire to sin will overcome you; but you should master it."
Cain said to his brother Abel, "Let us go into the field." And while they were in the field, Cain struck his brother Abel and killed him.
When the LORD said to Cain, "Where is your brother Abel?" Cain answered, "I do not know; am I my brother's keeper?" the LORD said, "What have you done? Hark! your brother's blood is crying to me from the ground. Even now you are condemned by the very ground that has opened to receive your brother's blood from your hand. Whenever you till the ground, it shall no longer yield to you its strength; you shall be a tramp and a wanderer on the earth."
Then Cain said to the LORD, "My punishment is more than I can bear. See, thou hast driven me out to-day from this land, and I shall no longer be able to worship thee; I shall become a tramp and a wanderer on the earth, and whoever finds me will kill me."
But the LORD said to him, "If any one kills you, he shall be punished sevenfold." So the LORD placed a mark on Cain, to keep any one who found him from killing him. And Cain went out from the LORD's presence and lived as a wanderer, away from Eden.
