Joel 2:10

2:10 The earth quakes before them;

the sky reverberates.

The sun and the moon grow dark;

the stars refuse to shine.

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!
