Isaiah 14:31-32. “Howl, O gate: cry, O city: thou, whole Palestina, art dissolved: for there shall come from the north a smoke, and none shall be alone to is appointed times. What shall one then answer the messengers of the nation? That the Lord hath founded Zion, and the poor of His people shall trust in it.”
Palestina is applied to the whole land of Canaan. In the Old Testament we heard a lot about the Philistines; Palestina and Philistia are one and the same. The city in this verse could be Ashdod, the largest city of the Philistines, but there is nothing definitive to tell us which city Isaiah is warning. It could be all the cities of Palestine that would be under siege.
From the north is a reference to the armies of Assyria that would destroy everything in their path. The smoke could refer to the burning of the villages along the way; it could also be the signal fires or torches that carry messages to other branches of the invading armies. None shall be alone would be better translated as there will be no stragglers in the invading armies; every soldier would be joined with every other soldier in the destruction.
In verse 32, the messengers of the nation(s) are those who come seeking safety; possibly, Jews from other nations. They will be told that there will be complete peace and safety for them in Zion, which has been founded by God Himself.
Both of these verses point to the time of the end, when Jesus will be the only world ruler, and all nations will be at peace.
