There are 2 wild beasts mentioned in Revelation, the scarlet-colored wild beast which is the image of “the wild beast OR currently the UN (previously the League of Nations).” I will note that it is hard to search for this information in the WOL and there has been dramatic decrease of the mention of the UN since 1990 (Watchtower Online Library) THE WILD BEAST= WT 2012 6/15 p.18 “the wild beast, Satan’s earthly political setup, will be goaded into an attack on God’s Kingdom.”
SCARLET-COLORED WILD BEAST=IMAGE OF THE WILD BEAST= LEAGUE OF NATIONS=UN
Revelation book chapter 28 p. 195 “Since World War II, the image of the wild beast—now manifested as the United Nations organization—has already killed in a literal way.
1954--This scarlet-colored wild beast represents a combination of nations, as the League of Nations was and the United Nations is.
2012 WT 6/15 p. 18 “This organization appeared after World War I and was known as the League of Nations. It disappeared with the onset of World War II. During that war, God’s people declared that according to the prophecy in Revelation, the image of the wild beast would ascend again. And rise it did—as the United Nations.
2022 May WT study article p. 10: “the image of the wild beast” and is described as “an eighth king.” This “king” is spoken of as coming into existence, then going out of existence, and later reappearing. How well this description fits the United Nations organization, which promotes the interests of the worldwide political system! It existed first as the League of Nations. Then it went out of existence during World War II. It later emerged again in its present-day form.
WILD BEAST (NOT TO BE CONFUSED WITH THE IMAGE OF THE WILD BEAST OR SOMETIMES REFERRED TO THE SCARLET-COLORED WILD BEAST)==LEAGUE OF NATIONS, THEN UN, THEN
WILD BEAST=SATAN’S EARTHLY POLITICAL SET UP
WT 2012 6/15 p.18 “the wild beast, Satan’s earthly political setup, will be goaded into an attack on God’s Kingdom.”
WT 1988 1/1 P. 16 “And a third warns against worship of “the wild beast,” Satan’s political system of things.”
IJWBQ ARTICE 74 “According to the last book in the Bible, 666 is the number, or name, of the wild beast with seven heads and ten horns that comes out of the sea. (Revelation 13:1, 17, 18) This beast is a symbol of the worldwide political system, which rules over “every tribe and people and tongue and nation.”
