Genesis 4:13

10 And he said, What hast thou done? the voice of thy brother's blood crieth to me from the ground.

11 And now [art] thou cursed from the earth, which hath opened her mouth to receive thy brother's blood from thy hand;

12 When thou tillest the ground, it shall not henceforth yield to thee its strength: A fugitive and a vagabond shalt thou be in the earth.

13 And Cain said to the LORD, My punishment [is] greater than I can bear.

14 Behold, thou hast driven me this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it will come to pass, [that] every one that findeth me will slay me.

15 And the LORD said to him, Therefore whoever slayeth Cain, vengeance shall be taken on him seven-fold. And the LORD set a mark upon Cain, lest any finding him should kill him.

16 And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.
