Genesis 4
9 Then the Lord said to Cain, “Where is your brother Abel?” “I don`t know,” he replied. “Am I my brother`s keeper?” 10 The Lord said, “What have you done? Listen! Your brother`s blood cries out to me from the ground. 11 Now you are under a curse and driven from the ground, which opened its mouth to receive your brother`s blood from your hand. 12 When you work the ground, it will no longer yield its crops for you. You will be a restless wanderer on the earth.” 13 Cain said to the Lord, “My punishment is more than I can bear. 14 Today you are driving me from the land, and I will be hidden from your presence; I will be a restless wanderer on the earth, and whoever finds me will kill me.” 15 But the Lord said to him, “Not so; anyone who kills Cain will suffer vengeance seven times over.” Then the Lord put a mark on Cain so that no one who found him would kill him. 16 So Cain went out from the Lord`s presence and lived in the land of Nod, east of Eden.
