'Speak a Word' in the Bible

Then Judah came near to him, and said, Oh my lord, let thy servant, I pray thee, speak a word in my lord's ears, and let not thy anger burn against thy servant; for thou art even as Pharaoh.

But the prophet, who shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.

The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to him that is weary: he wakeneth morning by morning, he wakeneth my ear to hear as the learned.

And whoever shall speak a word against the Son of man, it shall be forgiven him: but to him that blasphemeth against the Holy Spirit, it shall not be forgiven.
