'Speak the Word' in the Bible

The Centurion answered and said, "Sir, I am not worthy that thou shouldest come under my roof: but speak the word only, and my servant shall be healed.

And Paul said, "I am not mad, most dear Festus: but speak the words of truth and soberness.

Insomuch that many of the brethren in the Lord are boldened through my bonds, and dare more largely speak the word without fear.
