31 While they were trying to kill him, word came to the tribune of the cohort that all Jerusalem was in an uproar. 32 Immediately he took soldiers and centurions and ran down to them. When they saw the tribune and the soldiers, they stopped beating Paul. 33 Then the tribune came, arrested him, and ordered him to be bound with two chains; he inquired who he was and what he had done. 34 Some in the crowd shouted one thing, some another; and as he could not learn the facts because of the uproar, he ordered him to be brought into the barracks. 35 When Paul came to the steps, the violence of the mob was so great that he had to be carried by the soldiers. 36 The crowd that followed kept shouting, "Away with him!"
37 Just as Paul was about to be brought into the barracks, he said to the tribune, "May I say something to you?" The tribune replied, "Do you know Greek? 38 Then you are not the Egyptian who recently stirred up a revolt and led the four thousand assassins out into the wilderness?"

Commentary on Acts 21:27-40
(Read Acts 21:27-40)
In the temple, where Paul should have been protected as in a place of safety, he was violently set upon. They falsely charged him with ill doctrine and ill practice against the Mosaic ceremonies. It is no new thing for those who mean honestly and act regularly, to have things laid to their charge which they know not and never thought of. It is common for the wise and good to have that charged against them by malicious people, with which they thought to have obliged them. God often makes those a protection to his people, who have no affection to them, but only have compassion for sufferers, and regard to the public peace. And here see what false, mistaken notions of good people and good ministers, many run away with. But God seasonably interposes for the safety of his servants, from wicked and unreasonable men; and gives them opportunities to speak for themselves, to plead for the Redeemer, and to spread abroad his glorious gospel.
