After this I looked, and the sanctuary of the tent of witness in heaven was opened, and out of the sanctuary came the seven angels with the seven plagues, clothed in pure, bright linen, with golden sashes around their chests. And one of the four living creatures gave to the seven angels seven golden bowls full of the wrath of God who lives forever and ever, and the sanctuary was filled with smoke from the glory of God and from his power, and no one could enter the sanctuary until the seven plagues of the seven angels were finished. Then I heard a loud voice from the temple telling the seven angels, “Go and pour out on the earth [or land] the seven bowls of the wrath of God.” (Revelation 15:5-16:1)
Summarizing James Jordan, the bowls of Revelation constitute a kind of day of at-two-ment. Seven mediators, dressed in linen, come from the cherubim-throne and issue a return-to-sender for centuries of offering bowls, tribute bowls, purifying bowls, and seven-fold sprinklings. This is poured out not only upon the unbelieving land of Israel, but upon the entire old-covenant and old-creation world where Israel served as mediator for the nations.
After Jerusalem falls, Jesus is the only mediator left standing, the fountainhead of the new creation and the greater Solomon to whom kings and nations must gather.
