'Speak the Word' in the Bible

But the captain answered, "I am not fit for you to come under my roof, but simply speak the word, and my servant-boy will be cured.

And so I did not deem myself worthy even to come to you. But simply speak the word, and let my servant-boy be cured.

For He whom God has sent continues to speak the words of God, for God continues to give Him the Spirit without measure.
