'Ax Head' 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.
As one of them was cutting down a tree, the iron ax head fell into the water, and he cried out, “Oh, my master, it was borrowed!”
The prophet asked, "Where did it drop in?" When he showed him the spot, Elisha cut off a branch, threw it in at that spot, and made the ax head float.
