Ezekiel 36:29-30

“And I will save you from all your uncleannesses, and I will call for the corn and will multiply it, and lay no famine on you. And I will multiply the fruit of the tree and the increase of the field, that you receive no more the reproach of famine among the nations.”

The application is twofold, as ever the near and the far. The near refers to the fruitfulness of the land once the return from exile was complete, a fruitfulness which would bring joy and blessing. But its deeper significance is again the idea of the perfect world to come, when all needs would be met, all that a man could want would be available, and there would be no lack for anyone to draw attention to, so that no one could criticise God's provision for His own. God was offering His people perfection.
