Revelation 8:6-7

Then the seven angels who had the seven trumpets prepared themselves to sound them [initiating the judgments]. The first [angel] sounded [his trumpet], and there was [a storm of] hail and fire, mixed with blood, and it was hurled to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all the green grass was burned up. [Ex 9:13-35]
