Job 6:25

“How painful are honest words!
But what does your argument prove?

“Your words have helped the tottering to stand,
And you have strengthened feeble knees.

“O that you would be completely silent,
And that it would become your wisdom!

“Is there no limit to windy words?
Or what plagues you that you answer?

“How then will you vainly comfort me,
For your answers remain full of falsehood?”

“Now if it is not so, who can prove me a liar,
And make my speech worthless?”

And his anger burned against his three friends because they had found no answer, and yet had condemned Job.

There is one who speaks rashly like the thrusts of a sword,
But the tongue of the wise brings healing.

The wise in heart will be called understanding,
And sweetness of speech increases persuasiveness.

Death and life are in the power of the tongue,
And those who love it will eat its fruit.

Like apples of gold in settings of silver
Is a word spoken in right circumstances.

The Preacher sought to find delightful words and to write words of truth correctly.
