Hindu 
The Upanishads:  The Mystic Syllable Om

The word which all the Vedas rehearse,
And which all austerities proclaim,
Desiring which men live the life of religious studentship –
That word to you I briefly declare.
That is OM!


Buddhism
Dhammapada:  IV:  Flowers, 9

Like a beautiful flower that is both colorful and also fragrant, well-spoken words bear fruit in one who puts them into practice.


Zoroastrian
The Zend Avesta

O Gracious Love!
Demonstrate spiritual truth through Thy cosmic order.
O, Creator of Love!  Reveal the best words
Through Thy Good Mind living within us.


Taoism
Tao Te Ching:  81.  True Words are not Beautiful

True words are not beautiful,
Beautiful words are not true.
The good are not argumentative,
The argumentative are not good.
Knowers do not generalize,
Generalists do not know.
Sages do not accumulate anything,
But give everything to others


Native American
Black Elk Speaks:  p. 178

It was a clear evening with no wind, and it seemed that everything was listening hard to hear something.  While I was looking over there I felt that somebody wanted to talk to me.  So I stood up and began to sing the first song of my vision, the one that the two spirits had sung to me.
 
“Behold! A sacred voice is calling you!
All over the sky a sacred voice is calling!”



Judaism
The Poems of King David

The words of the Lord are pure words:  as silver tried in a furnace of earth, purified seven times.



Christian
Gospel of St. John, Prologue

In the beginning was the Word, and the Word was with God; and the Word was God.
Islam
Koran:  The Cow (115 – 117)

God is the originator
Of the heavens and the earth;
And whenever God decrees anything
God says to it, “Be!”
And it is.



Baha’i Faith
Baha’u’llah, The Seven Valleys, quoting Jelalu’din Rumi, The Mathavi

In thy soul of love build thou a fire
And burn all thoughts and words entire.

The words that enlighten the soul are more precious than jewels.
