Acts 21:35,36

‘And when he came on the stairs, so it was that he was borne of the soldiers for the violence of the crowd, for the multitude of the people followed after, crying out, “Away with him.” '

His strategy was necessary. For the incensed crowd,  even though we have already learned that they did not know why, continued to cry for his death. They were caught up in blood lust. So the soldiers bore him to the stairs leading into the fortress. These stairs actually led down into the court of the Gentiles. They were for quick access in case of trouble.

‘Away with him (aire auton).' Compare Luke 23:18, ‘aire touton' (see also John 19:15). Luke wishes us to identify the two situations. Jerusalem which had rejected its Messiah, has now finally rejected His servant. As far as Luke was concerned it was a final seal on its rejection, evidence of the lesson that he had made clear in chapter 12. They had closed the doors of the Temple on him, now they wanted rid of him totally.
