Exodus 14:2

That they turn - i. e. away from the wilderness, and go southwards, to the west of the Bitter Lakes, which completely separated them from the desert.

Pi-hahiroth - The place is generally identified with Ajrud, a fortress with a very large well of good water, situated at the foot of an elevation commanding the plain which extends to Suez, at a distance of four leagues. The journey from Etham might occupy two, or even three days.

Migdol - A tower, or fort, the “Maktal” of Egyptian monuments; it is probably to be identified with Bir Suweis, about two miles from Suez.

Baal-zephon - The name under which the Phoenicians, who had a settlement in Lower Egypt at a very ancient period, worshipped their chief Deity. There can be no doubt it was near Kolsum, or Suez. From the text it is clear that the encampment of the Israelites extended over the plain from Pi-hahiroth: their headquarters being between Bir Suweis and the sea opposite to Baal-Zephon. At Ajrud the road branches off in two directions, one leading to the wilderness by a tract, now dry, but in the time of Moses probably impassable (see next note); the other leading to Suez, which was doubtless followed by the Israelites.
