Genesis 9:4-6 KJV

4 But flesh with the life thereof, which is the blood thereof, shall ye not eat.

5 And 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.

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