Job 6:25

How steadfast are the words of truth! And which of you can rebuke or reprove them?

Thy words have set up those that were fallen, thou hast refreshed the weak knees.

Would God ye kept your tongue, that ye might be taken for wise men!

Shall not thy vain words come yet to an end? Or, hast thou yet any more to say?

How vain, then, is the comfort that ye give me? Are not your answers clean contrary to right and truth?"

Is it not so? Who will then reprove me as a liar, and say that my words are nothing worth?"

And with Job's three friends he was angry also, because they had found no reasonable answer to overcome him.

A slanderous person pricketh like a sword; but a wise man's tongue is wholesome.

Whoso hath a wise understanding is called to counsel; but he that can speak fair, getteth more riches.

Death and life stand in the power of the tongue; he that loveth it, shall enjoy the fruit thereof.

A word spoken in due season, is like apples of gold in a silver dish.

His diligence was to find out acceptable words, right scripture, and the words of truth.
