why in biblical times, did everybody walk around with a stick?
Probably becuz umm THEY DIDN'T HAVE CARS AND THEY HAD TO WALK FAR
Self-defense? Everyone was a bit whacko back then.
Why would you think that? Most people didn't. Shepherds would have but most people had no use for a stick.
Two types were used. A walking stick, and a shepherd's staff. It would be thousands of years until the ATV, and cattle prod were invented.
