As soon as the children of Israel were driven out of the land of Goshen, the new occupants would naturally commence the formation of a canal, for irrigating the land they had gained. Now, a great part of the valley of Seba Biar is lower than the level of the Nile at the height of the inundation, this was easily done. A canal from the eastern branch of the river, near Bubastes, did not require to be cut to a greater distance than seven miles, in order to allow the waters to fill the valley. By this operation, the irrigation could have been carried as far as the northern boundary of the bitter lakes, between Suez and the Mediterranean; and at least 20,000 acres of land gained for agricultural purposes. This irrigation would extend itself to the Serapeion—a distance of about forty-five miles from Bubastes, and about forty from the Red Sea.

Let us now observe the chronology of the events we have already noticed. Without pretending to offer any opinion on the disputed questions of Egyptian chronology, we shall adopt the dates given by Dr Nolan in his memoir on the use of the ancient cycles in settling the differences of chronologists, published in the Transactions of the Royal Society of Literature.[1] It must be observed, that the 430 years of the sojourning of the children of Israel in Egypt is to be computed from the call of Abraham, and not from the going down of Israel, as is explained by St Paul in the Epistle to the Galatians, chap. iii. v. 17.[2]

The Egyptians enjoyed a long period of prosperity after they had driven out the Israelites. Their national history, during a period of four hundred years, is recorded on their monuments; and, though not very intelligible in its details, it affords irrefragable proof that their country was always in a flourishing condition, and possessed a considerable commerce with other nations. The Egyptians, however, had as great an aversion to foreign traders as to shepherds; and it was long before they undertook any work for improving their commercial communications. At length, however, the canal, which had been carried as far as the longitudinal valley between the Red Sea and the Mediterranean, began to excite their attention as affording a cheap means of transport for that portion of the produce of the country which was purchased by the inhabitants of Arabia and of the shores of the Red Sea. We have the testimony of Aristotle, Strabo, and Pliny, that the project of forming a canal to unite the Nile with the Red Sea was entertained by Sesostris.[1] Aristotle says, "that Egypt, the most ancient seat of mankind, was formed by the river Nile, as appears from the examination of the country bordering on the Red Sea. One of the ancient kings attempted to form a navigable communication between the river and the sea; but Sesostris, finding that the waters of the Red Sea were higher than those of the Nile, both he and Darius, after him, desisted from the attempt, lest the lower part of the delta should be inundated with salt water." It is extremely difficult to ascertain what king is meant by Sesostris, since that name seems to have been given by the Greeks to more that one of the distinguished monarchs of the country. Aristotle, however, clearly refers in his account to the king he calls Sesostris, and to an earlier monarch. The one may have been Sethosis, who reigned about B.C. 1291, and the other, Sesonchis of Bubastes, the Shishac of Scripture, in the year B.C. 976. These sovereigns may have converted the canal of irrigation into a regular commercial route; and the last may have commenced the greater work of connecting it with the bitter lakes. The fear of inundating the Delta with salt water, by cutting through the northern shore of the Red Sea, and allowing a communication with the bitter lakes to remain always open, has been shown by the French engineers, whose report is printed in the great work on Egypt, to be no idle fear.[2]

Several circumstances combine to show that the completion of the canal, and the importance of opening a direct navigable communication between the Nile and the Red Sea, must have occupied more particularly the attention of Sesonchis than of the preceding kings. He was a native of Bubastes; and the seat of his power was in the Delta. The importance of this navigation for enriching his fellow-citizens, and placing the whole trade of the Delta, to the eastward, under his control, was evident; but the great wealth which might be gained from sharing in the trade on the Red Sea, was also forced on his attention, by the immense riches which Solomon had been able to accumulate on acquiring a share in this trade, which had been previously in the hands of the Phoenicians. Solomon had extended the trade he carried on in the Red Sea, by means of the ports on the gulf of Eloth, (Ailath,) far beyond its former bounds.[1] Now, as the grain and provisions, required for supplying the fleets in the Red Sea, and the greater part of the commercial population on its coasts, must have been drawn from Egypt by the port of Suez, and as Egypt must have afforded one of the most valuable markets for the produce of Arabia and India, it is not surprising that Sesonchis made great endeavours to obtain a share in a branch of commerce from which he had seen Solomon derive such wealth. From some reason, he abandoned the project of completing the canal to Suez; but, in order to secure a portion of Solomon's riches, he invaded Judea, and plundered Jerusalem.[2] "So Shishak king of Egypt came up against Jerusalem: and he took away the treasures of the house of the Lord, and the treasures of the king's house; he even took away all: and he carried away all the shields of gold which Solomon had made." That this Shishak, or Sesonchis of Bubastes, was the Sesostris alluded to by Aristotle, Strabo, and Pliny, though it cannot perhaps be positively proved, can nevertheless hardly admit of a doubt.
