Cain said to his brother Abel, “Let’s go out to the field.” And while they were in the field, Cain attacked his brother Abel and killed him.
Then the LORD said to Cain, “Where is your brother Abel? ”
“I don’t know,” he replied. “Am I my brother’s guardian? ”
Then He said, “What have you done? Your brother’s blood cries out to Me from the ground! So now you are cursed, alienated, from the ground that opened its mouth to receive your brother’s blood you have shed. If you work the ground, it will never again give you its yield. You will be a restless wanderer on the earth.”
But Cain answered the LORD, “My punishment is too great to bear! Since You are banishing me today from the soil, and I must hide myself from Your presence and become a restless wanderer on the earth, whoever finds me will kill me.”
Then the LORD replied to him, “In that case, whoever kills Cain will suffer vengeance seven times over.” And He placed a mark on Cain so that whoever found him would not kill him.
