Joel 2.

The Day of the Lord.

28 “And afterward,
    I will pour out my Spirit on all people.
Your sons and daughters will prophesy,
    your old men will dream dreams,
    your young men will see visions.
29 Even on my servants, both men and women,
    I will pour out my Spirit in those days.
30 I will show wonders in the heavens
    and on the earth,
    blood and fire and billows of smoke.
31 The sun will be turned to darkness
    and the moon to blood
    before the coming of the great and dreadful day of the Lord.
32 And everyone who calls
    on the name of the Lord will be saved;
