New Defender's Study Bible Notes
9:5 will I require. If the blood of animals is to be regarded as too sacred to be eaten, since it represents the “life” (or “soul”–Hebrew nephesh) of the animal and is acceptable as a substitutionary sacrifice for man’s sins, how much more sacred is the blood of man himself! His blood represents his life and, since he alone is “in the image of God,” the Creator of life, man’s blood is not even to be shed, let alone eaten! If either man or beast slays a man, that man or that animal is, judicially, to be slain himself, the reason being the divine sacredness of human life.
