I) Threats (1-4)
The chapter starts out with a description of the Lord riding on a swift cloud towards Egypt. This is an ironic statement as Baal had been described as a "rider of the cloud" in their mythical literature. Isaiah is using the same image of power to describe the Lord, and pointed out that both the idols and people of Egypt will be terrified when that happens .
God will bring disunity among the Egyptians and cause confusion, which their sorcerers, mediums and necromancers would not be able to help, and they will be ruled over by ruthless masters. (v 2-4)
II) Natural and economic disaster (5-10)
God will also bring natural disasters to Egypt by drying up the Nile, which is the main source of food such as fishes, vegetables, and also the manufacturing of flax and linen from the Papyrus. Those working in those industries will languish with despair as their livelihood will disappear.
III) Foolish counsel (11-15)
Egypt was well known for their wisdom. Even Solomon’s wisdom was compared to the wise men of Egypt in 1 Kings 4:30. However they were no match for the plans of God, just as their magicians were dumb-founded in front of Moses. They cannot even predict nor counsel against the rise of the Assyrians. There was nothing they can do to change what is coming.
IV) The five far-future prophecies about Egypt (16-24)
Five predictions are given for a future, starting with the words “in that day.”
The first (v16-17) is that Egyptians will be afraid of Judah. This may be referring to the millennial rule of Christ, but we already see that it is already partially fulfilled in the 20th century. Despite dozens of attacks by the Arabs after Israel's independence in 1948, Israel had never lost any battles. The military might of Egypt, whom Israel had always depended on, have been overpowered by Israel. Eventually, Egyptian President Anwar el-Sadat and Israeli Prime Minister Menachem signed a historic peace agreement that ended three decades of hostilities.
The second prophecy (v18) reveals that there will be five cities in Egypt that will ally with the Lord of Host and even change their language to Hebrew. One of the cities, “City of Destruction” is rendered as “City of the Sun” in the dead sea scroll and other manuscripts, which probably represented Heliopolis, the centre of worship for Ra, the Egyptian sun-god. This is an indication that culture and idolatry will be changed.
Thirdly, Egypt will come to know the Lord and worship him in the land. They will build altars and give sacrifices to the Lord. They will pray to the Lord for protection and a “savior and defender” will deliver them. It also says “the Lord will strike Egypt”, perhaps hinting that during the Armageddon Egypt will quickly recognize who the Lord is and repent and return to Him, and He will heal them. There will be a spirit of true worship spreading all over Egypt.
Fourthly, a highway will be built between Egypt and Assyria (present day Iraq). This highway will have to pass through Israel. I believe this will be a new highway, not the ones already present, and furthermore it is speaking about the spirit of co-operation and free trade among the nations between Egypt to Iraq. Assyria had the ambition of conquering the middle east to get to the resources in Egypt, but in future there will be peaceful commerce among the countries.
Lastly, these countries (including all territory the Assyrians have during Isaiah’s time) will become a blessing to the earth. (v24-25) Certainly, these middle-east countries have much resources (eg-oil, information technology, farming, real estate development, etc.) and are extremely rich. If united under Christ, they can be a source of wealth to the poorer countries on earth. Thus there will be an economic transformation that don’t just benefit themselves but the earth.
God will transform Egypt's culture, language, religion, military, and wealth to benefit the world!
IV) Application
As fallen men, our journey is not easy. Even on an individual basis, we have so much troubles with our family members, our jobs, our financials and our health. Yet, God’s plan for us is for the good – he will subject the whole earth under Christ, who will bring peace and prosperity to all in the end.
