Isaiah 18:2

(Verse 2) And it is said about their teaching and their language: You who send books of this age into the sea, the hostages of your perversity, and letters to deceive those who will read them. The swift messengers go to the high and foreign people, and the most wicked. For no ecclesiastics have so much zeal for good as heretics have for evil, and they believe they will gain advantage by deceiving others and destroying those who are already doomed. But this people is called exalted because of their pride: and foreign and wicked because they are estranged from God.

(Verse 2) Therefore, these people across the rivers of Ethiopia are sending messengers into the sea of this world, that is, their disciples, who are said to carry their volumes, rightly called papyrus vessels, that is, papers carried on the water, which are quickly erased. For just as books are quickly obscured and destroyed by water and moisture, so too their message and teaching, once it appears to possess some strength in the beginning, passes away and slips away. Therefore, through irony, it is said to them: O Angels of heretics, go quickly. These false apostles, deceitful workers, who transform themselves into apostles of Christ, are referred to as such by the blessed apostle Paul (2 Cor. XI). And go to the nation torn and ravaged: torn from God and torn apart by the bites of heretics. To a horrible people; for there is nothing more horrible than blasphemy, which lifts up its own mouth in arrogance. After which there is no other people; for every sin when compared to blasphemy is lighter. A people waiting, waiting, and trampled upon. For all heretics promise themselves celestial things, and they promise great things, and yet they are trampled upon by demons. Whose land the rivers have plundered, which do not have waters from the sky, but from the earth. For what corner is there, what remote wilderness of the earth, to which the polluted speech of heretics does not reach?

(Verse 2.) He who sends envoys to the sea, and in papyrus vessels on the waters. Go, swift angels, to a nation torn and ravaged, to a fearsome people after whom there is no other, to a nation waiting and trampled, whose rivers they have plundered. Among the Hebrews and Egyptians and the Egyptians themselves and the Egyptians, they are called by one name, Mesraim. This saying is have, so that no one may get stuck on the word, when they find a masculine word for a feminine gender, that is, for land a man, because even now it is said: He who sends envoys to the sea, that is, Mesraim itself, the Egyptian himself, because from Alexandria, which was then, as I said, called No, envoys were sent to Jerusalem and in papyrus vessels, that is, in letters, or ships, promising their help to them, saying: Go swiftly to the torn people of the Jews, and torn by the assault of the Assyrians; to the people once fearsome, who wielded the command of God, to whose power no one else can be compared: to a nation that always awaited the help of God, and yet is trampled by men: whose land rivers, that is, different kings, have ravaged. Others, however, think that the apostrophe is directed to the Lord, and the meaning is: O God, who sends prophets into the sea of this world, and like sailors through letters, warns the people, commanding them with your messages: go quickly to my torn and convulsed people, to the strongest people, who once terrified all nations around, who always waited for God's help, and because of the greatness of their sins, which they hope for, they do not deserve to receive it: whose land was ravaged by the kings of various nations, and so on. Eusebius of Caesarea, promising a historical interpretation in the title, wanders off into various meanings, so that when I read his books, I found something entirely different from what the index promised. Wherever he runs out of history, he moves on to allegory, and in this way he combines things that are separate, so that I marvel at his skill in joining together new elements of language into one unity of stone and iron. I mention this briefly, so that no one thinks that we have borrowed what we say from his sources; for even in the present chapter, he says that prophecy is directed against the Jews and Jerusalem, because at the beginning of the Christian faith they sent letters to all the nations, urging them not to…
