Flavius Josephus, The Wars of the Jews
William Whiston, A.M., Ed.

[457] NOW the people of Cesarea had slain the Jews that were among them on the very same day and hour [when the soldiers were slain], which one would think must have come to pass by the direction of Providence; insomuch that in one hour's time above twenty thousand Jews were killed, and all Cesarea was emptied of its Jewish inhabitants; for Florus caught such as ran away, and sent them in bonds to the galleys. Upon which stroke that the Jews received at Cesarea, the whole nation was greatly enraged; so they divided themselves into several parties, and laid waste the villages of the Syrians, and their neighboring cities, Philadelphia, and Sebonitis, and Gerasa, and Pella, and Scythopolis, and after them Gadara, and Hippos; and falling upon Gaulonitis, some cities they destroyed there, and some they set on fire, and then went to Kedasa, belonging to the Tyrians, and to Ptolemais, and to Gaba, and to Cesarea; nor was either Sebaste [Samaria] or Askelon able to oppose the violence with which they were attacked; and when they had burnt these to the ground; they entirely demolished Anthedon and Gaza; many also of the villages that were about every one of those cities were plundered, and an immense slaughter was made of the men who were caught in them.
