'Speaks' in the Bible

and you said, ‘Behold, the Lord our God has shown us His glory and His greatness, and we have heard His voice from the midst of the fire; we have seen today that God speaks with man, yet he [still] lives.

But the prophet who presumes to speak a word in My name which I have not commanded him to speak, or which he speaks in the name of other gods—that prophet shall die.’

When a prophet speaks in the name of the Lord and the thing does not happen or come true, that is the thing which the Lord has not spoken. The prophet has spoken it presumptuously; you shall not be afraid of him.
