Genesis 4:6-15

6Then the LORD said to Cain, “Why are you angry? Why is your face downcast?

7If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.”

8Now Cain said to his brother Abel, “Let’s go out to the field.” Samaritan Pentateuch, Septuagint, Vulgate and Syriac; Masoretic Text does not have “Let’s go out to the field.” While they were in the field, Cain attacked his brother Abel and killed him.

9Then the LORD said to Cain, “Where is your brother Abel?” “I don’t know,” he replied. “Am I my brother’s keeper?” 10The LORD said, “What have you done? Listen! Your brother’s blood cries out to me from the ground. 11Now you are under a curse and driven from the ground, which opened its mouth to receive your brother’s blood from your hand.

12When you work the ground, it will no longer yield its crops for you. You will be a restless wanderer on the earth.” 13Cain said to the LORD, “My punishment is more than I can bear.

14Today 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.” 15But the LORD said to him, “Not so Septuagint, Vulgate and Syriac; Hebrew Very well ; 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.
