Joel 2:5-11
2:5 Like the noise of chariots on the tops of mountains shall they leap, like the noise of a flame of fire that devoureth the stubble, as a strong people set in battle array.
2:6 Before their face the people shall be much pained: all faces shall gather blackness.
2:7 They shall run like mighty men; they shall climb the wall like men of war; and they shall march every one on his ways, and they shall not break their ranks:
2:8 Neither shall one thrust another; they shall walk every one in his path: and when they fall upon the sword, they shall not be wounded.
2:9 They shall run to and fro in the city; they shall run upon the wall, they shall climb up upon the houses; they shall enter in at the windows like a thief.
2:10 The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:
2:11 And the LORD shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for the day of the LORD is great and very terrible; and who can abide it?

Revelation 9:1-12
9:1 And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
9:2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
9:3 And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.
9:4 And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.
9:5 And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.
9:6 And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
9:7 And the shapes of the locusts were like unto horses prepared unto battle; and on their heads were as it were crowns like gold, and their faces were as the faces of men.
9:8 And they had hair as the hair of women, and their teeth were as the teeth of lions.
9:9 And they had breastplates, as it were breastplates of iron; and the sound of their wings was as the sound of chariots of many horses running to battle.
9:10 And they had tails like unto scorpions, and there were stings in their tails: and their power was to hurt men five months.
9:11 And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon.
9:12 One woe is past; and, behold, there come two woes more hereafter.
