'Fruitful' in the Bible

Now will I sing to my wellbeloved a song of my beloved touching his vineyard. My wellbeloved hath a vineyard in a very fruitful hill:

And shall consume the glory of his forest, and of his fruitful field, both soul and body: and they shall be as when a standardbearer fainteth.

Yet gleaning grapes shall be left in it, as the shaking of an olive tree, two or three berries in the top of the uppermost bough, four or five in the outmost fruitful branches thereof, saith the LORD God of Israel.

Is it not yet a very little while, and Lebanon shall be turned into a fruitful field, and the fruitful field shall be esteemed as a forest?

They shall lament for the teats, for the pleasant fields, for the fruitful vine.

Until the spirit be poured upon us from on high, and the wilderness be a fruitful field, and the fruitful field be counted for a forest.

Then judgment shall dwell in the wilderness, and righteousness remain in the fruitful field.
