Sam and companions camped at Banias, formerly the ancient city of Caesarea Philippi, September 17, 1867. They departed at 7:15am on September 18 and rode to Ain Mellaha. The Quaker City Itinerary used the spelling Baniyas, a city in northern Syria.

Caesarea Philippi or Caesarea Paneas was an ancient Roman city located at the southwestern base of Mount Hermon, adjacent to a spring, grotto, and related shrines dedicated to the god Pan, and called "Banias, Paneas", or Baniyas (not to be confused with Baniyas in northwestern Syria). The surrounding region was known as the "Panion".
