Adam Clarke on Genesis 9:5

Surely your blood - will I require; at the hand of every beast - This is very obscure, but if taken literally it seems to be an awful warning against cruelty to the brute creation; and from it we may conclude that horse-racers, hare-hunters, bull-baiters, and cock-fighters shall be obliged to give an account to God for every creature they have wantonly destroyed. Instead of חיה chaiyah, "beast," the Samaritan reads Yod Kaph chai, "living," any "living creature or person;" this makes a very good sense, and equally forbids cruelty either to men or brutes.
