“In this the children of God and the children of the devil are manifest: Whoever does not practice righteousness is not of God, nor is he who does not love his brother. For this is the message that you heard from the beginning, that we should love one another, not as Cain who was of the wicked one and murdered his brother. And why did he murder him? Because his works were evil and his brother’s righteous.” 1 John 3:10-12.
“Then Cain went out from the presence of the Lord and dwelt in the land of Nod on the east of Eden. 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.” Genesis 4:16-17.
“Now Adam knew Eve his wife, and she conceived and bore Cain, and said, ‘I have gotten a man from the Lord.’ Then she bore again, this time his brother Abel. Now Abel was a keeper of sheep, but Cain was a tiller of the ground.” Genesis 4:1-2.
“And they heard the sound of the Lord God walking in the garden in the cool of the day, and Adam and his wife hid themselves from the presence of the Lord God among the trees of the garden. Then the Lord God called to Adam and said to him, ‘Where are you?’ So he [Adam] said, ‘I heard Your voice in the garden, and I was afraid because I was naked; and I hid myself.’ And He said, ‘Who told you that you were naked? Have you eaten from the tree of which I commanded you that you should not eat?’ Then the man said, ‘The woman whom You gave to be with me, she gave me of the tree, and I ate.’ And the Lord God said to the woman, ‘What is this you have done?’ And the woman said, ‘The serpent deceived me, and I ate.’ So the Lord God said to the serpent: ‘Because you have done this, you are cursed more than all cattle, and more than every beast of the field; on your belly you shall go, and you shall eat dust all the days of your life.” Genesis 3:8-14
