'Word' in the Bible

So all of you approached me and said, "Let's send some men ahead of us to scout out the land and bring us back word as to how we should attack it and what the cities are like there."

For this is no idle word for you -- it is your life! By this word you will live a long time in the land you are about to cross the Jordan to possess."

He said to his father and mother, "I have not seen him," and he did not acknowledge his own brothers or know his own children, for they kept your word, and guarded your covenant.
