Whoever sheds man’s blood, his blood will be shed by man, for God made man in his own image.
Context
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.
7 And you, be ye fruitful, and multiply; bring forth abundantly in the earth, and multiply therein.
