'Speak the Word' in the Bible

For I am Jehovah: I will speak, what word I will speak and it shall be done; it shall no more be protracted: for in your days, O house of contradiction, I will speak the word, and I did it, says the Lord Jehovah.

For this, say to them, Thus said the Lord Jehovah: No more shall my words be protracted, for I will speak the word and it shall be done, says the Lord Jehovah.
