19 Your dead will live;
Their corpses will rise.
You who lie in the dust, awake and shout for joy,
For your dew is as the dew of the dawn,
And the earth will give birth to the departed spirits.
20 Come, my people, enter into your rooms
And close your doors behind you;
Hide for a little while
Until indignation runs its course.
This I believe is talking about the dead who will be raised, notice how it says that they are to hide in their rooms for a little while, UNTIL the indignation or the anger of God runs its course- so this happens before the wrath of God passes over. I believe that Isaiah is referring to those of his people- the Jews, those faithful ones who believed by faith in the promises who will be raised to life at the rapture along with those of the church age. I do not see this as a reference to the church of the age of grace alone, but that it includes all those who believe by faith including the OT faithful.
Psalm 83:2-5 (Parenthesis mine)
2 For behold, Your enemies make an uproar,
And those who hate You have exalted themselves.
3 They make shrewd plans against Your people,
And conspire together against Your treasured (hidden)ones.
4 They have said, “Come, and let us wipe them out as a nation,
That the name of Israel be remembered no more.”
5 For they have conspired together with one mind;
Against You they make a covenant:
This passage on the other hand is talking about an event on earth, the enemies of God are conspiring against the nation of Israel (the hidden ones) to wipe them out, so they will not be remembered on the earth. I do not see that these two passages are related. Take a look at the following passage; David is asking the Lord to "hide" him in the shadow of His wings from his enemies, the wicked who seek to destroy him and his people. Hide in the sense of protection, or refuge. Concealment from their enemies.
8 Keep me as the apple of the eye;
Hide me in the shadow of Your wings
9 From the wicked who despoil me,
My deadly enemies who surround me.
10 They have closed their unfeeling heart,
With their mouth they speak proudly.
11 They have now surrounded us in our steps;
They set their eyes to cast us down to the ground.
12 He is like a lion that is eager to tear,
And as a young lion lurking in hiding places.
13 Arise, O Lord, confront him, bring him low;
Deliver my soul from the wicked with Your sword,
How can the enemies of Israel listed in verses 6-8 of Psalm 83 (Edom, Ishmaelites, Moab, Hagrites, Gebal, Ammon, Amalek, Philistia, Tyre, and Assyria, conspire against those who have been raised from the dead and residing in the heavenly places? They have no power to do so. They as the passage explains conspire against the nation of Israel on earth, who happen to be God's chosen people, whom He protects and hides from their enemies, who will not allow the plans of their enemies to succeed. This to me may be more in line with the woman who flees to the wilderness for God's protection in revelation 12, than with those who are raised from the dead.
The writer of the article asks this question:
Q. Psalm 83:3 says “They have taken crafty counsel against thy people, and consulted against thy hidden ones.” The word “they” refers to the Arab confederates, and “thy people” refers to the nation of Israel. Who are the “hidden ones?” Could this be the raptured Church? If so, it would be a pretty strong hint that the Church is raptured before the battle of Psalm 83 takes place. What do you think?
Just because a word is used that is the same word or a word with similar meaning in another passage does not necessarily mean that they speak concerning the same thing. The passage in Psalms tells us who the hidden ones are- the nation of Israel.
