Thayer's Greek Lexicon

 Caesarea = "severed"
1. Caesarea of Philippi was situated at the foot of Lebanon near the
sources of the Jordan in Gaulanitis, and formerly called Paneas;
but afterward being rebuilt by Philip the tetrarch, it was called
by him Caesarea, in honour of Tiberias Caesar; subsequently called
Neronias by Agrippa II, in honour of Nero.
2. Caesarea of Palestine was built near the Mediterranean by Herod
the Great on the site of Strabo's Tower, between Joppa and Dora.
It was provided with a magnificent harbour and had conferred upon
it the name of Caesarea, in honour of Augustus. It was the
residence of Roman procurators, and the majority of its
inhabitants were Greeks.
