Acts 22:25-30 ESV
But when they had stretched him out for the whips, Paul said to the centurion who was standing by, “Is it lawful for you to flog a man who is a Roman citizen and uncondemned?” When the centurion heard this, he went to the tribune and said to him, “What are you about to do? For this man is a Roman citizen.” So the tribune came and said to him, “Tell me, are you a Roman citizen?” And he said, “Yes.” The tribune answered, “I bought this citizenship for a large sum.” Paul said, “But I am a citizen by birth.” So those who were about to examine him withdrew from him immediately, and the tribune also was afraid, for he realized that Paul was a Roman citizen and that he had bound him.
But on the next day, desiring to know the real reason why he was being accused by the Jews, he unbound him and commanded the chief priests and all the council to meet, and he brought Paul down and set him before them.
