Ezekiel 38:16

38:16 You will advance against my people Israel like a cloud covering the earth. In the latter days I will bring you against my land so that the nations may acknowledge me, when before their eyes I magnify myself through you, O Gog.

Jeremiah 4:13

4:13 Look! The enemy is approaching like gathering clouds.

The roar of his chariots is like that of a whirlwind.

His horses move more swiftly than eagles.”

I cry out, “We are doomed, for we will be destroyed!”

Joel 2:2

2:2 It will be a day of dreadful darkness,

a day of foreboding storm clouds,

like blackness spread over the mountains.

It is a huge and powerful army

there has never been anything like it ever before,

and there will not be anything like it for many generations to come!
