Genesis 4:13 ASV

¹¹  And now cursed art thou from the ground, which hath opened its mouth to receive thy brother's blood from thy hand;

¹²  when thou tillest the ground, it shall not henceforth yield unto thee its strength; a fugitive and a wanderer shalt thou be in the earth.

¹³  And Cain said unto Jehovah, My punishment is greater than I can bear.

¹⁴  Behold, thou hast driven me out this day from the face of the ground; and from thy face shall I be hid; and I shall be a fugitive and a wanderer in the earth; and it will come to pass, that whosoever findeth me will slay me.

¹⁵  And Jehovah said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And Jehovah appointed a sign for Cain, lest any finding him should smite him.
