Only Merchants 'buy and sell', Consumers only buy, they are the 'end-user'. Part of that is worshipping 'the image' from Re:13. It is the abomination in Matt:24 as well as Da:11:31
The false throne from the 2Thess:2 prophecy can only stand on holy ground in Jerusalem during the 3 1/2 days the two witnesses are in the grave.
Zec:13 ending is part of the war against the Nations that starts Zec:14. 2/3 die and 1/3 remain alive, a handful at the end of Re:11 run away and make it to the mountains, from there they watch Satan's Babylon be melted by the fire used on Sodom.
