'Vain words' in the Bible

whether there be any unrighteousness in my tongue, or vain words in my mouth.

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

Behold, ye stand in your own conceit, as though ye knew all things. Wherefore then do ye go about with such vain words,

In every labour there is some profit; but only vain words bringeth forth penury.

Therefore, if ye will not tell me the dream, ye shall all have one judgment: But ye feign and dissemble with vain words which ye speak before me, to put off the time. Therefore tell me the dream, and so shall I know - if ye can show me - what it meaneth."

Let no man deceive you with vain words. For through such things cometh the wrath of God upon the children of unbelief.
