31 As they were trying to kill him, word reached the commander of the Roman regiment that all Jerusalem was in an uproar. 32 He immediately called out his soldiers and officers and ran down among the crowd. When the mob saw the commander and the troops coming, they stopped beating Paul. 33 Then the commander arrested him and ordered him bound with two chains. He asked the crowd who he was and what he had done. 34 Some shouted one thing and some another. Since he couldn't find out the truth in all the uproar and confusion, he ordered that Paul be taken to the fortress. 35 As Paul reached the stairs, the mob grew so violent the soldiers had to lift him to their shoulders to protect him. 36 And the crowd followed behind, shouting, "Kill him, kill him!"
37 As Paul was about to be taken inside, he said to the commander, "May I have a word with you?" "Do you know Greek?" the commander asked, surprised. 38 "Aren't you the Egyptian who led a rebellion some time ago and took 4,000 members of the Assassins out into the desert?"

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.
