Genesis 4:15 YLT

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.
