From the tower of Syene - Or, as in the margin, “Migdol” (“tower”) was about two miles from Suez. “Syene” was the most southern town in Egypt, on the borders of Ethiopia, in the Thebaid, on the eastern bank of the Nile. The modern Assvan lies a little to the northeast of the ancient Syene.
We have no record of the circumstances of the Chaldsaean invasion of Egypt, but it is possible that it did not take place until after the fall of Tyre. We gather of what nature it must have been by comparing the description of the results of Assyrian conquest (Isaiah 37:25 ff). Minute fulfillment of every detail of prophecy is not to be insisted upon, but only the general fact that Egypt would for a time, described as 40 years, be in a state of collapse. No great stress is to be laid on the exact number of years. The number of years passed in the wilderness became to the Hebrews a significant period of chastisement.
Nebuchadnezzars occupation of Egypt was of no long duration, and his ravages, though severe, must have been partial. Peace with Babylon was favorable to the development of home-works, but since the peace was in truth subjugation, it was hollow and in fact ruinous. Further, it is to be remembered that God fulfils His decree by a gradual rather than an immediate process. The ravages of Nebuchadnezzar were the beginning of the end, and all the desolation which followed may be looked upon as a continuous fulfillment of God’s decree. The savage fury with which Cambyses swept over Egypt amply realized all that Ezekiel foretold. Many places recovered some wealth and prosperity, but from the time of Herodotus the kingdom never again became really independent. Egyptian rulers gave place to Persian, Persian to the successors of Alexander the Great, who gave place in turn to Rome. So thoroughly was the prophecy of Ezekiel fulfilled Ezekiel 29:14-15.
