Acts 28:20

For this cause, therefore, have I called for you, to see you and to speak with you, because that for the hope of Israel I am bound with this chain.

There was a flourishing congregation in Rome at this time, and Paul could well have devoted his entire time to the believers already gathered. But, as in other places, he here deliberately called the most influential Jews together, still adhering to his rule: to the Jew first and also to the Greek, Romans 1:16. The decree of Claudius banishing the Jews from Rome. Acts 18:2, had meanwhile been recalled, and the Jews had again flocked to the capital. When the leading Jews responded to his invitation and met in the place designated by Paul, he laid some matters of a personal nature before them. He wanted, above all, to remove any prejudices that they might entertain with respect to him, first, on account of his imprisonment; secondly, on account of the fact that he had appealed to the emperor; thirdly, to remove any effects of slanderous reports which may possibly have been brought from Jerusalem. He told them that he had done nothing, was not guilty of any offense either against the people of the Jews or against the customs and usages of the fathers, and yet had been delivered into the hands of the Romans. Paul tactfully refers to his arrest as being occasioned only indirectly by the Jews. When the Romans had given him a hearing, they had wanted to release him, since they found no cause of death in him, not a single crime having been proved against the apostle. But when the Jews then objected, he had been obliged to appeal to Caesar: hut not in the sense, as Paul hastens to add, as though he had any accusation to bring against his own people. But it was for this reason that he had called for them, had asked them to meet with him in order that he might see them and speak to them, have a conference with them. For he assures them that he is wearing this chain, which they all could see, he was surrounded with this evidence of imprisonment, on account of the hope of Israel. The one hope of Israel was that concerning the Messiah; to Him all the prophets looked forward, of Him all the sages had spoken. And it was because Paul preached of the fulfillment of all these hopes and predictions and prophecies in the person of Jesus Christ of Nazareth that the enmity had struck him which resulted in his arrest.
