'Speak the Word' in the Bible

Take counsel together, and it shall come to nothing; speak the word, and it shall not stand: for God is with us.

The centurion answered and said, Lord, I am not worthy that you should come under my roof: but speak the word only, and my servant shall be healed.

And many of the brethren in the Lord, becoming confident by my bonds, are much more bold to speak the word without fear.
