'Lash' in the Bible

the commanding officer ordered Paul to be brought back into the barracks. He told them to interrogate Paul by beating him with a lash so that he could find out the reason the crowd was shouting at Paul in this way.

When they had stretched him out for the lash, Paul said to the centurion standing nearby, "Is it legal for you to lash a man who is a Roman citizen without a proper trial?"
