Kenneth Kitchen says that one translation of the Hebrew name "Pi-hahiroth" is "mouth of the Hiroth" with the word 'Hiroth' either a word for canal or the name of a canal entering a branch of the Nile or a lake. and suggests locations north or northeast of Ismailia.
Pi-hahiroth has also been identified as 'a place where sedge grows' or ‘a place where reeds grow’. This has resulted in much discussion and speculation about an alternative location. Some have argued that, as a marshy place with reeds, its location to the north of Suez was more likely. Other have thought it to be near Ajrud, a fortress between Etham and Suez. There was nevertheless consensus that the location of Pi-hahiroth, if it was a real place, was close to Egypt.
The Haggada holds that Pi-hahiroth is the same as Pi-Tum.
