“And you will ascend, you will come like a storm, you will be like a cloud to cover the land, you and all your hordes and many people with you (compare Joel 2:1-11).”
The description is not one of warfare but of taking over the country. There is no mention of warfare. This could well indicate a show of strength in Palestine by a Persian army on the way to Egypt, during the reign of one of the Persian kings, an army which included contingents from all the nations mentioned.
It could also indicate an invasion by dark forces. Thus the days of Jesus saw an increase in demon possessions and manifestations of Satan like never before or since. Satan and his minions came like a storm and like a cloud covered the land. The language here is apocalyptic, the storm, the covering cloud descending, the gathering of the hordes. All speak of the enemies of ‘the last days', the times of the Messiah. The Messiah had to face His enemies. And once the Messiah had risen and received His throne the attacks turned on His people.
But that these attacks on God's people would continue is clear in Revelation where powerful forces of evil are also described, and they will continue on to the end. In mind here in Ezekiel, therefore, may well be all attacks on God's people throughout this present age, ‘the latter days', but especially that last great ‘battle' at the end of time when God will bring in His final judgments. And with the certainty of attack comes the certainty of deliverance.
