"By the Jewish law it was a crime punishable with death for an uncircumcised person to enter the inner courts of the sacred edifice. Paul had been seen in the city in company with Trophimus, an Ephesian, and it was conjectured that he had brought him into the temple. This he had not done; and being himself a Jew, his act in entering the temple was no violation of the law. But though the charge was wholly false, it served to arouse the popular prejudice. As the cry was taken up and borne through the temple courts, the throngs gathered there were thrown into wild excitement. The news quickly spread through Jerusalem, “and all the city was moved, and the people ran together.” AA 407.1"
"(For they had seen before with him in the city Trophimus an Ephesian, whom they supposed that Paul had brought into the temple.)"
EGW explains the context surrounding the events in Acts 21:29, including the accusation involving Trophimus. She also quotes Acts 21:27.
"That an apostate from Israel should presume to profane the temple at the very time when thousands had come there from all parts of the world to worship, excited the fiercest passions of the mob. “They took Paul, and drew him out of the temple: and forthwith the doors were shut.” AA 407.2"
"And all the city was moved, and the people ran together: and they took Paul, and drew him out of the temple: and forthwith the doors were shut."
EGW directly quotes Acts 21:30, describing the mob's actions against Paul.
"“some cried one thing, some another, among the multitude: and when he could not know the certainty for the tumult, he commanded him to be carried into the castle. And when he came upon the stairs, so it was, that he was borne of the soldiers for the violence of the people. For the multitude of the people followed after, crying, Away with him.” AA 407.3"
"And some cried one thing, some another, among the multitude: and when he could not know the certainty for the tumult, he commanded him to be carried into the castle."
The EGW passage directly quotes Acts 21:34, making it an explicit allusion.
