Acts 28:17
And it came to pass, that after three days Paul called the chief of the Jews together: and when they were come together, he said unto them, Men and brethren, though I have committed nothing against the people, or customs of our fathers, yet was I delivered prisoner from Jerusalem into the hands of the Romans.
This took place when Paul arrived at Rome as a prisoner, while the Christians in Italy who had received his epistle to the Romans were eagerly looking for his visit. By the centurion's permission he stayed seven days with them at the seaport. When they learned of his approach they started out to meet and welcome him. They had not expected to see him come as a prisoner, but they loved him the more because of his sufferings.
Three days after arriving in Rome, Paul called the chief and leading Jews together. He told them that though he had done nothing against the Jewish people or the customs and ancestral customs of the fathers, yet he had been delivered and brought as a prisoner from Jerusalem to the Romans at Rome. He met with them first so they could hear his own account before his opponents turned them against him.
He spoke carefully, directly and kindly, leaving out and not dwelling on the abuse, plots and assassination plots he had suffered. He spoke in this way because he meant to defend the truth and honor and uphold the gospel, not to complain about his treatment or to win sympathy and seek sympathy for himself. His declaration while accused and held as a prisoner, with imprisonment and impending death under Nero, makes him an example of faith standing against worldly power.
