Joel 2:21 (KJV) Fear not, O land; be glad and rejoice: for the Lord will do great things.
22 Be not afraid, ye beasts of the field: for the pastures of the wilderness do spring, for the tree beareth her fruit, the fig tree and the vine do yield their strength.

24 And the floors shall be full of wheat, and the vats shall overflow with wine and oil.
