'Ax' in the Bible

For instance, he may have accompanied his friend to go to a forest to cut trees. Then he swung his axe to cut some wood, but the ax head flew off the handle and hit his friend, so that he died. The killer may flee to one of these cities to live.

"When you attack a city and have to fight against it for many days, don't destroy its trees by cutting them down with an ax. You may eat from them, but you must not cut them down. Are the trees of the field human beings, that you would come and attack them?
