Pi-hahiroth (Hebrew: פִּי החִירֹת) is the fourth station of the Exodus. The fifth and sixth stations Marah and Elim (Bible) are located on the Red Sea. The biblical books Exodus and Numbers refer to Pi-hahiroth as the place where the Israelites encamped between Migdol and the sea, opposite Baal Zephon, while awaiting an attack by Pharaoh, prior to crossing the Red Sea. Reaching Pi-Hahiroth involved turning back from the direction they had been travelling.
Those positing a Hebrew name have speculated "Pi-hahiroth" might mean "mouth of the gorges", descriptive of its location as the end of a canal or river.
William Smith, in his Dictionary of Greek and Roman Geography, tentatively identifies Pi-hahiroth with Arsinoe, Egypt at the northern end of the Gulf of Suez. Strong's Concordance simply locates Pi-hahiroth as 'a place on the eastern border of Egypt'.
However, some writers would locate Pi-Hahiroth along the Gulf of Aqaba, at Nuweiba Beach, Egypt, about 300 km to the east, or near the Straits of Tiran at the southern end of the Sinai Peninsula and the Gulf of Aqaba, which is about 400 km south-east of Suez.
