Revelation 9;1-4, 13-15
V1 The fifth angel blew his trumpet and i saw one who was fallen from heaven and to him was given the key to the bottomless pit. V 2 When he opened it , smoke poured out as though from some huge furnace and the sun and the air were darkened by smoke. V3 Then the locust came from the smoke and descended onto the earth and were given power to sting like scorpion. V4 The were told not hurt the grass or plants or trees, but to attack those people who did not have the mark of God on their foreheads.
V13 The sixth angel blew his trumpet and I heard a voice speaking from the four horns of the golden alter that stands before the throne of God, V14 saying to the sixth angel, “Release the four mighty demons held bound at the great River Euphrates.” V15 They had been kept in readiness for that year and month and day and hour, and now they were turned loose to kill a third of all mankind.
Rev 10; 1-3
V1 Then i saw another mighty angel coming down from heaven, surrounded by a cloud, with a rainbow over his head; his face shone like the sun and his feet flashed with fire. V2 And he held open in his hand a small scroll. He set his right foot on the sea and his left foot on the earth, V3 and gave a great shout- it was like the roar of a lion and the seven thunders crashed their reply.
