Genesis 4:9-12

And Jehovah said unto Cain, Where is Abel thy brother? And he said, I know not: am I my brother’s keeper? And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground. And now cursed art thou from the ground, which hath opened its mouth to receive thy brother’s blood from thy hand; 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.
