The high priest - informed him against Paul - They supposed that as Felix, to please them, on the resignation of his government, had left Paul bound, so Festus, on the assumption of it, would, to please them, deliver him into their hand; but, as they wished this to be done under the color of justice, they exhibited a number of charges against Paul, which they hoped would appear to Festus a sufficient reason why a new trial should be granted; and he be sent to Jerusalem to take this trial. Their motive is mentioned in the succeeding verse.

The center of work has shifted from Jerusalem to Antioch, the capital of the Greek province of Syria, the residence of the Roman governor of the province.
