Thematic Bible: Cain fears

Behold, you have driven me out this day from the face of the earth; and from your face shall I be hid; and I shall be a fugitive and a wanderer in the earth; and it shall come to pass, that anyone that finds me shall slay me. And the LORD said unto him, Therefore whosoever slays Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.
