Almost as soon as Paul gets situated in Rome, he calls the leading Jews together to give an explanation of how he came to be there. Perhaps because of the trying weather through the winter, the Jews had not heard any complaints against Paul from Judea. The Jews are interested though in hearing more about Paul's sect: one that is spoken against everywhere.

[Act 28:16-22 NASB] 16 When we entered Rome, Paul was allowed to stay by himself, with the soldier who was guarding him. 17 After three days Paul called together those who were the leading men of the Jews, and when they came together, he [began] saying to them, "Brethren, though I had done nothing against our people or the customs of our fathers, yet I was delivered as a prisoner from Jerusalem into the hands of the Romans. 18 "And when they had examined me, they were willing to release me because there was no ground for putting me to death. 19 "But when the Jews objected, I was forced to appeal to Caesar, not that I had any accusation against my nation. 20 "For this reason, therefore, I requested to see you and to speak with you, for I am wearing this chain for the sake of the hope of Israel." 21 They said to him, "We have neither received letters from Judea concerning you, nor have any of the brethren come here and reported or spoken anything bad about you. 22 "But we desire to hear from you what your views are; for concerning this sect, it is known to us that it is spoken against everywhere."
