Joel 2:1-2

1Blow the trumpet in Zion. Tell the people on the Lord's hill that they must watch for trouble. All the people who live in this country will be afraid. They will be afraid because the day of the Lord is coming. It is very near.

2That day will be sad and dark. There will be dark clouds. A great big army is coming. It comes across the sky like light in the morning. A great army like this has never come before. And it will never come again in future years.
