'Scourge' in the Bible

And the crowd rose up too against them; and the praetors, having torn off their clothes, commanded to scourge them.

the commander ordered him to be brought into the barracks, directing that he be examined with the scourge, so he could discover the reason they were shouting against him like this.

And as they bound him with thongs, Paul said unto the centurion that stood by, Is it lawful for you to scourge a man that is a Roman, and uncondemned?
