31 As they were trying to kill him, news came up to the commanding officer of the regiment that all Jerusalem was in an uproar. 32 Immediately he took soldiers and centurions, and ran down to them. They, when they saw the chief captain and the soldiers, stopped beating Paul. 33 Then the commanding officer came near, arrested him, commanded him to be bound with two chains, and inquired who he was and what he had done. 34 Some shouted one thing, and some another, among the crowd. When he couldn’t find out the truth because of the noise, he commanded him to be brought into the barracks. 35 When he came to the stairs, it happened that he was carried by the soldiers because of the violence of the crowd; 36 for the multitude of the people followed after, crying out, “Away with him!”
37 As Paul was about to be brought into the barracks, he asked the commanding officer, “May I speak to you?”
He said, “Do you know Greek? 38 Aren’t you then the Egyptian, who before these days stirred up to sedition and led out into the wilderness the four thousand men of the Assassins?”

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.
