Genesis 4:13-15

Young's Literal Translation

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.
