Joel 2:1

The Locusts’ Devastation

2:1 Blow the trumpet in Zion;

sound the alarm signal on my holy mountain!

Let all the inhabitants of the land shake with fear,

for the day of the Lord is about to come.

Indeed, it is near!

Joel 2:30-31

2:30 I will produce portents both in the sky and on the earth –

blood, fire, and columns of smoke.

2:31 The sunlight will be turned to darkness

and the moon to the color of blood,

before the day of the Lord comes –

that great and terrible day!
