Isaiah 19:11

Surely the princes of Zoan are fools, the counsel of the wise counsellors of Pharaoh is become brutish: how say ye unto Pharaoh, I am the son of the wise, the son of ancient kings?

The verse stands in the first part of Isaiah, chapters 1 to 39, among the prophecies and historical accounts given during Isaiah's active work in the public concerns of the rulers and the people as God's messenger to the nation. It is a single distinct prophecy published at its own time and on its own occasion and afterward brought together with the others into one collection. It is not part of the wholly future contemplation of chapters 40 to 66 concerning deliverance from Babylonian captivity and deliverance from sin and error through the Messiah. Its position does not settle its date under Jotham, Ahaz, and Hezekiah, because chapters are transposed and inserted out of chronological order.

The verse belongs to a prophecy concerning Egypt. As part of Isaiah 19:1-13, it describes the revolutions and future state of Egypt and foretells its subjection to the Macedonians under Alexander the Great. Together with the other prophecies concerning Egypt, it shows Egypt invaded, conquered, spoiled, and given into the hand of strangers, diminished so that it becomes the basest of the kingdoms and no more rules over the nations. The prophecy refers to the preaching of the Gospel in both Egypt and Assyria in New Testament times.

A great part of the prophecy had already been fulfilled in Egypt, probably centuries ago. The verse is not a prophecy expected to be fulfilled in modern times.
