Genesis 4:9 And the Lord said to Cain: Where is thy brother Abel? And he answered: I know not: am I my brother's keeper?
4:10 And he said to him: What hast thou done? the voice of thy brother's blood crieth to me from the earth.
4:11 Now therefore cursed shalt thou be upon the earth, which hath opened her mouth and recieved the blood of thy brother at thy hand.
4:12 When thou shalt till it, it shall not yield to thee its fruit: a fugitive and a vagabond shalt thou be upon the earth.
4:13 And Cain said to the Lord: My iniquity is greater than that I may deserve pardon.
4:14 Behold thou dost cast me out this day from the face of the earth, and from thy face I shall be hid, and I shall be a vagabond and a fugitive on the earth: every one therefore that findeth me, shall kill me.
4:15 And the Lord said to him: No, it shall not so be: but whosoever shall kill Cain, shall be punished sevenfold. And the Lord set a mark upon Cain, that whosoever found him should not kill him.
4:16 And Cain went out from the face of the Lord, and dwelt as a fugitive on the earth at the east side of Eden.
