Adam Clarke on Acts 22:24

Examined by scourging - As the chief captain did not understand the Hebrew language, he was ignorant of the charge brought against Paul, and ignorant also of the defense which the apostle had made; and, as he saw that they grew more and more outrageous, he supposed that Paul must have given them the highest provocation; and therefore he determined to put him to the torture, in order to find out the nature of his crime. The practice of putting people to the rack, in order to make them confess, has, to the disgrace of human nature, existed in all countries.
