Zechariah 14:16-21 says, “And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles. And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain. And if the family of Egypt go not up, and come not, that have no rain; there shall be the plague, wherewith the LORD will smite the heathen that come not up to keep the feast of tabernacles. This shall be the punishment of Egypt, and the punishment of all nations that come not up to keep the feast of tabernacles. In that day shall there be upon the bells of the horses, HOLINESS UNTO THE LORD; and the pots in the LORD's house shall be like the bowl's before the altar. Yea, every pot in Jerusalem and in Judah shall be holiness unto the LORD of hosts: and all they that sacrifice shall come and take of them, and seethe therein: and in that day there shall be no more the Canaanite in the house of the LORD of hosts.”
In keeping with the Amil understanding of this reading, Egypt continued to exist after the First Advent. Those within that ancient nation that refuse to yield to Christ will one join that rebellion throng throughout time that are condemned at the final judgment. It should be noted, Jerusalem will be holy and no strangers will pass through her anymore. The word interpreted “strangers” means foreigner or profane. Yet the Premil understanding of Jerusalem is quite the contrary. It sees countless rebellious strangers visiting it from the nations will go from year to year. Egypt is alive and kicking here!
Joel 3:12-19 says, “Let the heathen be wakened, and come up to the valley of Jehoshaphat: for there will I sit to judge all the heathen round about. Put ye in the sickle, for the harvest is ripe: come, get you down; for the press is full, the fats overflow; for their wickedness is great. Multitudes, multitudes in the valley of decision: for the day of the LORD is near in the valley of decision. The sun and the moon shall be darkened, and the stars shall withdraw their shining. The LORD also shall roar out of Zion, and utter his voice from Jerusalem; and the heavens and the earth shall shake: but the LORD will be the hope of his people, and the strength of the children of Israel. So shall ye know that I am the LORD your God dwelling in Zion, my holy mountain: then shall Jerusalem be holy, and there shall no strangers pass through her any more. And it shall come to pass in that day, that the mountains shall drop down new wine, and the hills shall flow with milk, and all the rivers of Judah shall flow with waters, and a fountain shall come forth of the house of the LORD, and shall water the valley of Shittim. Egypt shall be a desolation, and Edom shall be a desolate wilderness"
There is no avoiding the fact that there will be no Egypt left to populate a future millennium at Christ's coming. This is a constant point in Scripture. You need to acknowledge this.
