4:13And Cain said unto the LORD, My punishment is greater than I can bear.

4:14Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass, that every one that findeth me shall slay me.

4:15And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.

9:5And surely your blood of your lives will I require; at the hand of every beast will I require it, and at the hand of man; at the hand of every man's brother will I require the life of man.

9:6Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man.

27:43Now therefore, my son, obey my voice; and arise, flee thou to Laban my brother to Haran;

27:44And tarry with him a few days, until thy brother's fury turn away;

27:45Until thy brother's anger turn away from thee, and he forget that which thou hast done to him: then I will send, and fetch thee from thence: why should I be deprived also of you both in one day?
