The Elect have Entered into their Chambers-Chambers of Death?

Isaiah 26:20 Come, my people, enter thou into thy chambers, and shut thy doors about thee: hide thyself as it were for a little moment, until the indignation be overpast.

21 For, behold, the Lord cometh out of his place to punish the inhabitants of the earth for their iniquity:

And,

Proverbs 7:27 Her house is the way to hell, going down to the chambers of death.

Q. Could there be a good chamber too: Song of Solomon 1:4? And Proverbs 24:4?- as well as a bad chamber?

A. The 5 wise virgins (bride of Christ) enter in and the door is shut. The chamber points to where the elect bride is kept for the marriage feast of the Lamb during Judgment Day.

Job 37:9 Out of the south cometh the whirlwind: and cold out of the north.

The word "south" is same word as chamber. The whirlwind ties in with judgment.
