As Bart Belteshassur pointed out, Ezekiel proclaimed that Egypt would be desolated for 40 years:
11 Neither man nor livestock will pass through it on foot, and it will not be inhabited for 40 years. 12 I will make the land of Egypt the most desolate of lands, and its cities will be the most desolate of cities for 40 years; and I will scatter the Egyptians among the nations and disperse them among the lands.” 13 “‘For this is what the Sovereign Lord Jehovah says: “After 40 years I will gather back the Egyptians from the peoples where they were scattered; (Ezekiel 29:11-13)
However, it never happened. But the Watchtower Society, the champion of fraud and deception, gives the following misleading defense:
At Ezekiel 29:1-16 a desolation of Egypt is foretold, due to last 40 years. This may have come after Nebuchadnezzar’s conquest of Egypt . While some commentaries refer to the reign of Amasis (Ahmose) II, the successor of Hophra, as exceedingly prosperous during more than 40 years, they do so primarily on the testimony of Herodotus, who visited Egypt over a hundred years later. But as the Encyclopædia Britannica (1959, Vol. 8, p. 62) comments on Herodotus’ history of this period (the “Saitic Period”): “His statements prove not entirely reliable when they can be checked by the scanty native evidence.” The Bible Commentary by F. C. Cook, after noting that Herodotus even fails to mention Nebuchadnezzar’s attack on Egypt , says: “It is notorious that Herodotus, while he faithfully recorded all that he heard and saw in Egypt , was indebted for his information on past history to the Egyptian priests, whose tales he adopted with blind credulity. . . . The whole story [by Herodotus] of Apries [Hophra] and Amasis is mixed with so much that is inconsistent and legendary that we may very well hesitate to adopt it as authentic history. It is by no means strange that the priests should endeavour to disguise the national dishonour of having been subjected to a foreign yoke.” (Note B., p. 132) Hence, while secular history provides no clear evidence of the prophecy’s fulfillment, we may be confident of the accuracy of the Bible record. (Insight, Egypt, pp. 686-699)
So, though the Society tries to undermine Herodotus' reliability, Leolaia provided us all the records found of Amasis' reign, which is an overwhelming proof that Nebuchadnezzar could not desolate Egypt:
