"And they took their journeyª° from Succoth,ª¹ and encampedª° in Etham,ª in the edgeª of the wilderness.ª" {Exd 13:20}
Succoth:
Supposed to be the Suche mentioned by Pliny and the Scenas Mandrorum, in the Antonine Itinerary. The Editor of Calmet places it at Birket el Hadji, or "the Pilgrims' pool," a few miles east of Cairo.
Etham:
This was evidently situated towards the north point of the Red sea. Calmet supposes it to be the same as Buthus or Butham, mentioned by Herodotus, who places it in Arabia, on the frontiers of Egypt.
