Joel 2:29-32

2:29 Even on male and female servants

I will pour out my Spirit in those days.

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!

2:32 It will so happen that

everyone who calls on the name of the Lord will be delivered.

For on Mount Zion and in Jerusalem there will be those who survive,

just as the Lord has promised;

the remnant will be those whom the Lord will call.
