But what is ‘the sea,’ by the side of which the Israelites encamped? Its identification has been the subject of much controversy—a fact, however, which ceases to astonish us when we find that the Hebrew writers themselves were uncertain about it. While in the narrative of the Exodus ‘the sea’ crossed by the Israelites is carefully distinguished from the ‘Yâm Sûph’ or ‘Reedy Sea,’ at which they subsequently arrived, there are other passages in the Old Testament, more especially of a poetical nature, in which the two seas are confounded together. Two irreconcileable systems of geography are thus presented to us which have hitherto made the geography of the Exodus an insoluble problem. In the narrative, however, all is clear and exact. The children of Israel, it was determined, instead of following the northern road to Palestine, should march along that which led to ‘the wilderness of the Yâm Sûph.’ But between them and this wilderness lay the Egyptian wall of fortification, which extended from the marshes in the north to the Gulf of Suez, or its prolongation, in the south. It was only when they had turned the southern end of the wall by crossing ‘the sea’ that they entered ‘the wilderness of the wall,’ where they wandered for three days without finding water (Exod. xv. 22). Later they came to the palm-grove of Elim, and then after that to the Yâm Sûph (Numb. xxxiii. 10). The Yâm Sûph was well known to Hebrew geography, and corresponded with the modern Gulf of Aqaba. It was upon the Yâm Sûph, at Elath and Ezion-geber, ‘in the land of Edom,’ that Solomon built his ships (1 Kings ix. 26); and after the capture of Arad, in the extreme south of Canaan, the Israelites marched ‘from mount Hor by the way of Yâm Sûph, in order to compass the land of Edom’ (Numb. xxi. 4). Elim is but another form of Elath, the ruins of which lie close to Aqaba, while the town of Sûph lay ‘over against’ the wilderness in the plains of Moab (Deut. i. 1). The Yâm Sûph, in fact, so erroneously rendered ‘the Red Sea’ in the Authorised Version, was the Gulf of Aqaba. The sister Gulf of Suez was called by the Hebrews ‘the Egyptian Sea’ (Isa. xi. 15), a very appropriate name, since it was enclosed on either side by Egyptian territory. From the days of the third dynasty to those of the Ptolemies, Mafkat, the Sinaitic peninsula, was included among the provinces of Egypt.
