Adam had sexual relations with his wife Eve, and she became pregnant and gave birth to Cain. Eve said, “With the Lord’s help, I have given birth to a man.”
I will make you and the woman enemies to each other. Your descendants and her descendants will be enemies. One of her descendants will crush your head, and you will bite his heel.”
After God forced humans out of the garden, he placed angels and a sword of fire that flashed around in every direction on its eastern border. This kept people from getting to the tree of life.
Adam had sexual relations with his wife Eve again, and she gave birth to a son. She named him Seth and said, “God has given me another child. He will take the place of Abel, who was killed by Cain.”
Do not be like Cain who belonged to the Evil One and killed his brother. And why did he kill him? Because the things Cain did were evil, and the things his brother did were good.
