Joel, chapter 2:

23 So rejoice, O sons of Zion, and be glad in the LORD your God; For He has given you the early rain for your vindication. And He has poured down for you the rain, the early and latter rain as before.

24 The threshing floors will be full of grain, and the vats will overflow with the new wine and oil.

25 Then I will make up to you for the years that the swarming locust has eaten, The creeping locust, the stripping locust and the gnawing locust, My great army which I sent among you.

26 You will have plenty to eat and be satisfied And praise the name of the LORD your God, Who has dealt wondrously with you; then My people will never be put to shame.

27 Thus you will know that I am in the midst of Israel, And that I am the LORD your God, And there is no other; And My people will never be put to shame.

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

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

30 I will display wonders in the sky and on the earth, Blood, fire and columns of smoke.

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

32 And it will come about that whoever calls on the name of the LORD Will be delivered; For on Mount Zion and in Jerusalem There will be those who escape, As the LORD has said, Even among the survivors whom the LORD calls.
