Paul Escorted by Roman Cavalry at Nightby emmanuel_higgins

Acts 23:32

On the morrow they left the horsemen to go with him, and returned to the castle:

Paul had been brought by night as far as Antipatris, and this verse follows that night removal. On the next morning after the night journey the foot soldiers left Paul and returned to the fortress at Jerusalem. Their return marked the end of their part in the escort, once the danger of the first stage was past.

The horsemen did not return but continued with him onward to Caesarea. They kept escorting him through the following day's journey until the transfer was complete. There at Caesarea he was delivered safely to Felix the governor.
