It’s my understanding that there is a concept known as the “Great Day of the Lord,” which refers to Judgment Day. Mentions of “that day” in Scripture are references to this. I have noted Isaiah 3:17-24 which includes the term “that day” and seems to be a perfect description of conditions for Jewish women in a 1940’s slave labor camp:
The Lord will give the daughters of Zion itching heads and will uncover their nakedness. … .
Instead of a belt, a rope;
instead of a scent, a stink;
instead of a pretty dress, a sack;
instead of nice hair; a shaven scalp;
and brand marks instead of beauty.
In my opinion this passage indicates that the world is now experiencing the “Great Day of the Lord” and the length of that “day” may be over one hundred years since we have not yet experienced God’s final judgment which is spelled out in Isaiah 66:15-16.
For see how YHWH comes in fire,
His chariots like the tempest,
to assuage His anger with burning,
His threats with brilliant fire.
For by fire will YHWH execute judgement,
and by His sword against all mankind.
The victims of YHWH will be many.
My thought is that this passage is a description of nuclear war on a global scale. It seems to tie in with Jeremiah 25:32-33. It’s going to be a rough ride, folks.
