Revelation 9 describes the sounding of the fifth and sixth trumpets, bringing two significant judgments on the earth. The fifth trumpet releases locusts from the bottomless pit, symbolizing punishment upon those without God's seal, while the sixth trumpet unleashes a massive army destined to destroy a third of mankind as part of the imminent destruction of Jerusalem. Despite these calamities, survivors fail to repent of their evil deeds, which included idol worship and persecution of Christians.
