Joel 2:28-32

28“It shall come about after this That I shall pour out My Spirit on all mankind; And your sons and your daughters will prophesy, Your old men will dream dreams, Your young men will see visions.

29Even on the male and female servants I will pour out My Spirit in those days.

30I will show signs and wonders [displaying My power] in the heavens and on the earth, Blood and fire and columns of smoke.

31The sun will be turned into darkness And the moon into blood Before the great and terrible day of the Lord comes.

32And it shall come about that whoever calls on the name of the Lord Will be saved [from the coming judgment] For on Mount Zion and in Jerusalem There will be those who escape, As the Lord has said, Even among the remnant [of survivors] whom the Lord calls.
