27 Now when the seven days were almost ended, the Jews from Asia, seeing him in the temple, stirred up the whole crowd and laid hands on him, 28 crying out, "Men of Israel, help! This is the man who teaches all men everywhere against the people, the law, and this place; and furthermore he also brought Greeks into the temple and has defiled this holy place." 29 (For they had previously seen Trophimus the Ephesian with him in the city, whom they supposed that Paul had brought into the temple.)

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.
