In all the story of the waters remember this first order, “let the waters be gathered together.”  To take their assigned places they were obliged to flow, and, once arrived there, to remain in their place and not to go farther.  Thus in the language of Ecclesiastes, “All the waters run into the sea; yet the sea is not full.” Eccl. i. 6, 7.  Waters flow in virtue of God’s order, and the sea is enclosed in limits according to this first law, “Let the waters be gathered together unto one place.”  For fear the water should spread beyond its bed, and in its successive invasions cover one by one all countries, and end by flooding the whole earth, it received the order to gather unto one place.  Thus we often see the furious sea raising mighty waves to the heaven, and, when once it has touched the shore, break its impetuosity in foam and retire.  “Fear ye not me, saith the Lord.…which have placed the sand for the bound of the sea.” Jer. v. 22.  A grain of sand, the weakest thing possible, curbs the violence of the ocean.  For what would prevent the Red Sea from invading the whole of Egypt, which lies lower, and uniting itself to the other sea which bathes its shores, were it not fettered by the fiat of the Creator?  And if I say that Egypt is lower than the Red Sea, it is because experience has convinced us of it every time that an attempt has been made to join the sea of Egypt i.e. the Mediterranean. to the Indian Ocean, of which the Red Sea is a part. Geminum mare…quod Rubrum dixere nostri…in duos dividitur sinus.  Is qui ab oriente Persicus est…altero sinu Arabico nominato.  Plin. vi. 28.  Thus we have renounced this enterprise, as also have the Egyptian Sesostris, who conceived the idea, and Darius the Mede who afterwards wished to carry it out. This illustration is taken from the work on which Basil has been so largely dependent, the Meterology of Aristotle (i. 14, 548).  Pliny (vi. 33) writes:  “Daneos Portus, ex quo navigabilem alveum perducere in Nilum, qua parte ad Delta dictum decurrit lxii. mill. D. Pass. intervallo, quod inter flumen et Rubrum mare inter est, primus omnium Sesostris Ægypti rex cogitavit; mox Darius Persarum; deinde Ptolemæus sequens” (i.e. Ptolemy II.) “…deterruit inundationis metus, excelsiore tribus cubitis Rubro mari comperto quam terra Ægypti.”  Herodotus (ii. 158) attributes the canal to Necho.  Strabo (xvii. 804) says Darius, in supposing Egypt to lie lower than the sea, was ψευδεῖ πεισθείς.  The early canal, choked by sand, was reopened by Trajan, and choked again.  Amron, Omar’s general, again cleared it, but it was blocked a.d. 767.  The present Suez Canal, opened in 1869, follows a new course.
