Joel 2:1-6

Sound the trumpet in Jerusalem! Raise the alarm on my holy mountain! Let everyone tremble in fear because the day of the LORD is upon us. It is a day of darkness and gloom, a day of thick clouds and deep blackness. Suddenly, like dawn spreading across the mountains, a great and mighty army appears. Nothing like it has been seen before or will ever be seen again. Fire burns in front of them, and flames follow after them. Ahead of them the land lies as beautiful as the Garden of Eden. Behind them is nothing but desolation; not one thing escapes. They look like horses; they charge forward like warhorses. Look at them as they leap along the mountaintops. Listen to the noise they make—like the rumbling of chariots, like the roar of fire sweeping across a field of stubble, or like a mighty army moving into battle. Fear grips all the people; every face grows pale with terror.
