New Defender's Study Bible Notes
19:5 dried up. The troubles experienced by Egypt described in Isaiah 19:5-15 were sent as a judgment from God, associated with the Assyrian and later Babylonian invasions and captivities. See also Ezekiel 29–30. Although the secular histories of Egypt during these periods (from about 720 B.C. to about 570 B.C.) are sparse (the defeated Egyptians would be unlikely to record such events due to their national pride), there is good reason to believe that they were all fulfilled as written. It is known that the Nile flow following drought periods in its headwater region did diminish seriously on various occasions in the past.
