'Speak a Word' in the Bible

Only, the prophet who presumeth to speak a word in My name -- that which I have not commanded him to speak -- and who speaketh in the name of other gods -- even that prophet hath died.

Take counsel, and it is broken, Speak a word, and it doth not stand, Because of Emmanu-El!'

Because that they have done folly in Israel, and commit adultery with the wives of their neighbours, and speak a word in My name falsely that I have not commanded them, and I am He who knoweth and a witness -- an affirmation of Jehovah.

For I am Jehovah, I speak, The word that I speak -- it is done, It is not prolonged any more, For, in your days, O rebellious house, I speak a word, and I have done it, An affirmation of the Lord Jehovah.'

therefore say unto them: Thus said the Lord Jehovah: None of my words are prolonged any more, When I speak a word -- it is done, An affirmation of the Lord Jehovah!'

And whoever may speak a word against the Son of Man it shall be forgiven to him, but whoever may speak against the Holy Spirit, it shall not be forgiven him, neither in this age, nor in that which is coming.
