The book of Proverbs deals with many practical subjects as well as spiritual ones. In this verse we are given advice on hunting. Today men are slaughtering animals for wicked reasons. Many elephants and rhinos are killed for their tusks and horns and their bodies are left to rot. Other animals are slain for just the sport of it and their heads and bodies are stuffed to hang on a wall for a trophy of man's prowess, while the meat was discarded.
Bulls are slain for men just to watch the sport of bull fighting.
Cock fighting is another sport where the cocks are put together to see which one will kill the other. Gambling is usually associated with this sport. We could name other atrocities of killing animals which take place with evil motives. Some people consider killing animals as an evil thing and have become vegetarians because they do not want to kill anything. Certainly, this is a noble thing, however, the Bible does not speak against killing animals for food.
