Genesis 4:14

11 and now, cursed [art] thou from the ground, which hath opened her mouth to receive the blood of thy brother from thy hand;

12 when thou tillest the ground, it doth not add to give its strength to thee -- a wanderer, even a trembling one, thou art in the earth.`

13 And Cain saith unto Jehovah, `Greater is my punishment than to be borne;

14 lo, Thou hast driven me to-day from off the face of the ground, and from Thy face I am hid; and I have been a wanderer, even a trembling one, in the earth, and it hath been -- every one finding me doth slay me.`

15 And Jehovah saith to him, `Therefore -- of any slayer of Cain sevenfold it is required;` and Jehovah setteth to Cain a token that none finding him doth slay him.

16 And Cain goeth out from before Jehovah, and dwelleth in the land, moving about east of Eden;

17 and Cain knoweth his wife, and she conceiveth, and beareth Enoch; and he is building a city, and he calleth the name of the city, according to the name of his son -- Enoch.
