Eusebius of Caesarea

Now one can consider that the prophecy has not been fulfilled if the following are true: if the Egyptians in our own time cannot be seen to have abandoned the gods of their fathers and calling on the God of the prophets; throughout every town and city in the country of Egypt there are not altars built to the God that previously only the Hebrews acknowledged; the idols have not been shaken.… How can we deny that the prophecies of ages past have been fulfilled? They promised beforehand that the Lord would not come to Egypt in an incorporeal manner but on a light cloud, or better "on a thick light," which is the meaning of the Hebrew word. This figuratively speaks of his incarnation. The prophecy continues by calling him a human being who is the Savior, saying, "And he shall send to them a man who is a savior." The Hebrew here is, "And he shall send to them a savior who will save them." This clear demonstration leads me to conclude that there is no doubt of the time of the promise of the appearing of the Lord.
