'Words' in the Bible

"But [when you] pray, do not babble repetitiously like the pagans, for they think that because of their many words they will be heard.

"Therefore everyone who hears these words of mine and does them will be like a wise man who built his house on the rock.

And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand.

And it happened when Jesus finished these words the crowds were amazed at his teaching,

And whoever does not welcome you or listen to your words, shake off the dust from your feet [as you] are going out of that house or [that] town.

For by your words you will be vindicated, and by your words you will be condemned."

Heaven and earth will pass away, but my words will never pass away.
