'Producing' in the Bible

For before harvest, when the flower is perfect, And the blossom is producing unripe fruit, Then hath one cut the sprigs with pruning hooks, And the branches he hath turned aside, cut down.

So will My word be which goes out of My mouth;It will not return to Me void (useless, without result),Without accomplishing what I desire,And without succeeding in the matter for which I sent it.

Producing the fruit of the lips, 'Peace, peace,' to the far off, and to the near, And I have healed him, said Jehovah.
