Acts XXVI. 30-32
“And when he had thus spoken, the king rose up, and the governor, and Bernice, and they that sat with them: and when they had gone aside, they talked between themselves, saying, This man does nothing worthy of death or of bonds. Then said Agrippa unto Festus, This man might have been set at liberty, if he had not appealed unto Cæsar.”
