2 Esdras 15:27-37

27 Terrible disasters have already come upon the world, and there is no escape. You have sinned against God, and he will not rescue you.
28 Then in the east you will suddenly see a fearsome sight.
29 Arab armies with many chariots will advance like dragons. As soon as they start out, the sound of their hissing will spread across the world and bring fear and trembling to everyone who hears it.
30 The Carmonians will come out of the forest in a fierce rage like wild boars advancing in full strength to attack the dragons. With their tusks they will tear up a large part of Assyria,
31 but the dragons will unite their forces, regain their former strength, and win the victory. They will turn and pursue the wild boars,
32 who will be thrown into panic, beaten into silence, and forced to turn and run.
33 The wild boars will be ambushed in Assyria, and one of them will be killed. This will bring fear and panic to their army and indecision to their kings.
34 Then suddenly clouds - terrible, angry storm clouds - will cover the sky from one end to the other.
35 They will collide head-on and release their violence upon the earth. The blood of war will be as deep as a horse's belly
36 or someone's thigh or a camel's knee.
37 Everywhere on earth people will tremble in fear at the horrible sight.
