The ensign or standard, is a flag representing the colors of the army unit. When it is seen or hoisted, that was a signal to rally around the flag and follow those colors into battle or wherever they might lead you.
The hiss, comes from Isa. 7:18, wherein the Lord will call or whistle or blow a flute or some instrument, and those who hear, will come to its call. In the ancient world, bees were called out of their hives into the fields and back to the hives, with flute like calls.
And so it is used here to demonstrate that the Lord controls history, not man. He uses His power and intellect and plan, and ability and so forth, to call forth the nations from the far distant places, to rally and come to participate in the destruction being executed.
In this case, Judah was the target of Gods judgment.
This principle teaches how God controls history by means of the use of peoples and nations when they pursue their own agendas regardless of whether they are righteous or not.
God can use evil to rise up against evil, or evil to rise up against righteous, or righteous to rise up against evil, and these combinations have occurred over and over, again and again throughout history. Peoples have risen up to combat people, but God in all of His wisdom, knew about these conflicts in eternity past, long before they were to occur.
And while these situations did occur in the history of Israel and Judah, their enemies did not come from the far reaches of the world. That truth will not occur until the end of history in the Tribulation, as well as at the very end of the Millennium. Assyria, Babylon, Persia, Greece, and even Rome may have been considered the ends of the earth in that time, but the real ends of the earth will not become operational until the final days of history.
In the Tribulation, the world will be filled with evil and evil will rise up against evil and destroy itself.
At the end of the Millennium evil will rise up against the righteous and evil will be destroyed.
At the end of our dispensation, the Church Age, evil will rise up in a great apostasy from the far reaches of the world, and God will remove the righteous in the Rapture, leaving the evil to its own devices. And even out of that pit, many will rise up and believe in Christ and some will survive the worldwide destructive forces until the Second Advent.
The point here is, that even when people, or organizations, or political parties, or nations, or empires seem to have their own agenda, it is really God who is Jesus Christ, that is in control of their inevitable actions.
Man does not control his own destiny. Man cannot cause his own birth, cannot time his own death, and cannot control his afterlife once he is gone from this world.
