Both Azotus and Caesarea were located on the Mediterranean coast. Azotus was the ancient Philistine city of Ashdod, about 35 kilometres north of Gaza. Caesarea was named after August Caesar. Most likely Philip’s journey from Azotus to Caesarea took a number of weeks or months. The next time we read about him is in Acts 21:8, where he is said to live in Caesarea together with his four daughters.
40 But Philip found himself at Azotus, and as he passed through he preached the gospel to all the towns until he came to Caesarea.
