31 Now as they were seeking to kill him, news came to the commander of the garrison that all Jerusalem was in an uproar. 32 He immediately took soldiers and centurions, and ran down to them. And when they saw the commander and the soldiers, they stopped beating Paul. 33 Then the commander came near and took him, and commanded him to be bound with two chains; and he asked who he was and what he had done. 34 And some among the multitude cried one thing and some another. So when he could not ascertain the truth because of the tumult, he commanded him to be taken into the barracks. 35 When he reached the stairs, he had to be carried by the soldiers because of the violence of the mob. 36 For the multitude of the people followed after, crying out, "Away with him!"
37 Then as Paul was about to be led into the barracks, he said to the commander, "May I speak to you?" He replied, "Can you speak Greek? 38 Are you not the Egyptian who some time ago stirred up a rebellion 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.
