'Word' in the Bible

Then they sat on the ground with him seven days and nights, but no one spoke a word to him because they saw that his suffering was very intense.

A word was brought to me in secret;my ears caught a whisper of it.

These are but the fringes of His ways;how faint is the word we hear of Him!Who can understand His mighty thunder?

After a word from me they did not speak again;my speech settled on them like dew.
