what does the bible say?

Genesis 4:16 tells us: “Then Cain went out from the presence of the LORD and dwelt in the land of Nod on the east of Eden.” The only information the Bible gives us is that the land of nod was east of Eden. The Hebrew word for Nod means “wandering.”

Part of the punishment Cain incurred for murdering his brother Able, was that of being a fugitive and a vagabond in a land apart from his kinsman. Genesis 4:11-12 states: “So now you are cursed from the earth, which has opened its mouth to receive your brother’s blood from your hand. When you till the ground, it shall no longer yield its strength to you. A fugitive and a vagabond you shall be on the earth.’”
