Pi-hahiroth: Pi̇hachiroth, "the mouth of Chiroth," as it is rendered by the LXX. Dr. Shaw is of opinion, that Chiroth denotes the valley which extends from the wilderness of Etham to the Red Sea. "This valley," he observes, "ends at the sea in a small bay made by the eastern extremities of the mountains (of Gewoubee and Attackah, between which the valley lies) which I have been describing, and is called Tiah-Beni-Israel, i.e., the road of the Israelites, by a tradition that is still kept up by the Arabs, of their having passed through it; so it is also called Baideah, from the new and unheard of miracle that was wrought near it, by dividing the Red sea, and destroying therein Pharaoh, his chariots, and his horsemen."
Migdol: The word Migdol signifies a tower, and hence some have supposed that it was a fortress which served to defend the bay. But the LXX render it Μαγδωλος, Magdolus, which is mentioned by Herodotus, Hecateus, and others, and is expressly said by Stephanus (de Urb.) to be πολις Αιγυπτον, "a city of Egypt." This Bochart conjectures to have been the same as Migdol - see the parallel passages. Jer 44:1, Jer 46:14, Eze 29:10, Heb
Baalzephon: This may have been the name of a town or city in which Baal was worshipped; and probably called zephon, from being situated on the north point of the Red sea, near the present Suez.
