Genesis 4:13

10 And he said, What hast thou done? With a voice, the shed-blood of thy brother is crying out to me from the ground,

11 Now therefore, accursed, art thou,—from the ground which hath opened her mouth, to receive the shed-blood of thy brother at thy hand.

12 Though thou till the ground, it shall not go on to give its vigour to thee. A wanderer and a fugitive, shalt thou be in the earth.

13 And Cain said unto Yahweh—Greater is my punishment than I can bear.

14 Lo! thou has driven me out, this day, from off the face of the ground And from thy face, shall I be hid, So shall I become a wanderer and a fugitive in the earth. And it shall come to pass, whosoever findeth me, will slay me.

15 And Yahweh said to him—Not so, whosoever slayeth Cain seven—fold, shall it be avenged. So Yahweh set, for Cain, a sign, that none finding him should smite him.

16 So Cain went forth from the presence of Yahweh,—and dwelt in the land of Nod, eastward of Eden.
