One sentence in the Moffatt translation, from verse 15, catches the thought clearly: "And yet one day from the heights of heaven a spirit shall breathe unto us [or, into us]." Then follows the effects of that Spirit. In this context, just as in Psalm 104:30, things begin in a state of destruction and remain that way until God sends forth His Spirit. Then, regeneration of both the people and the land takes place, and the transformation of both occurs.
