“For the day of vengeance is in mine heart, and the year of my redeemed is come.”
Walled cities we're not to go out in the Jubilee release, but unwalled cities we're considered part of the country and did go. The land can be redeemed by the rightful owner, providing all of the conditions are met. I believe this is whats happening in Revelation Chapter 4 and 5, it the right of redemption using the very framework and Laws God provided with the Law of Moses which Jesus fulfilled in the flesh. These laws and requirements are being used to redeem all of creation. I further believe its these very ordinances that Satan is trying to overcome, to break the everlasting covenant, (see Isaiah ch 24) likely to prevent this very event from becoming legally possible upon the Earth which he currently has dominion over.
Revelation 16:19, Jerusalem is divided into three parts
Also, earlier Jerusalem is given over to the gentiles for 42 months,
I believe this is why,
there is much more going on here, and we're told much more than most realize, but that doesn't mean I'm right, just my conjecture,
but if so, it also means that the age of the Gentiles is coming to a close.
