Yes, spiritual house is made of physical people and when the 8th king comes to power, no one that wants to be part of the spiritual house will support the 8th king, therefore physical people will be captives and or killed by the 8th king. The taking captive/killing of these that make up the spiritual house is how
the judgment comes upon God's house. It is how the temple/holy place is trampled for 42 months during the 8th king rule. This is not a WTS/JW event, it is a
WORLDWIDE event which includes
all people/mankind of the entire inhabited earth. JWs are people/mankind inhabiting the earth, so they can be said to be part of the spiritual house if they are refusing to support the 8th king when that time comes. But likewise, all others that are also refusing to support the 8th king are part of that spiritual house/temple being trampled upon during those 42 months.
[
5 you yourselves as living stones are being built up into
a spiritual house to be a holy priesthood, in order to offer up
spiritual sacrifices acceptable to God through Jesus Christ.]
[
21 In union with him
the whole building, being harmoniously joined together, is growing into
a holy temple for Jehovah.]
[
19 Then he said: “Here I am causing you to know what will happen i
n the final part of the denunciation, because it is for
the appointed time of the end.]
[
17 For it is
the appointed time for the judgment to start with
the house of God.]
[
10 ...
the hour of test,
which is to come upon the entire inhabited earth, to put to the test those dwelling on the earth.]
[
18 Young children, it is
the last hour, and just as you have heard that
the antichrist is coming, even now many antichrists have appeared, from which fact we know that it is the last hour.] [
4 He stands in opposition and exalts himself above every so-called god or object of worship, so that he sits down in the temple of God, publicly showing himself to be a god.] [
5 It was given a mouth speaking great things and blasphemies, and it was given authority to act for 42 months. 7 It was permitted to wage war with the holy ones and conquer them, and it was given authority over every tribe and people and tongue and nation. 10 If anyone is meant for captivity, he will go into captivity. If anyone will kill with the sword, he must be killed with the sword. This is where it calls for endurance and faith on the part of the holy ones.] [
6 And I saw another angel flying in midheaven, and he had everlasting good news
to declare to those who dwell on the earth, to every nation and tribe and tongue and people. 7 He was saying in a loud voice:
“Fear God and give him glory, because the hour of judgment by him has arrived, so worship the One who made the heaven and the earth and the sea and the springs of water.”
9 Another angel, a third, followed them, saying in a loud voice:
“If anyone worships the wild beast and its image and receives a mark on his forehead or on his hand, 10 he will also drink of the wine of the anger of God that is poured out undiluted into the cup of His wrath,]
[
31 And arms will stand up, proceeding from him; and they will
profane the sanctuary, the fortress, and remove the constant feature.
“And they will
put in place the disgusting thing that causes desolation.
32 “And those who act wickedly against the covenant,
he will lead into apostasy by means of smooth words.
But the people who know their God will prevail and act effectively. 36 “
The king will do as he pleases, and he will exalt himself and magnify himself above every god; and against the God of gods he will speak astonishing things. And
he will prove successful until the denunciation comes to a finish; because what is determined must take place. 37 He will show no regard for the God of his fathers; nor will he show regard for the desire of women or for any other god, but
he will magnify himself over everyone.]

9 Out of one of them came another
horn, a small one, and it grew very great toward the south and toward the east and toward the Decoration.
10 It grew so great that it reached all the way to the army of the heavens, and it caused some of the army and some of the stars to fall to the earth, and it trampled them down.
11 It exalted itself even against the Prince of the army,
and from him the constant feature was taken away, and the established place of his sanctuary was thrown down.]
