'Lord Has Spoken' in the Bible

Who is the wise man, that may understand this? and who is he to whom the mouth of the LORD has spoken, that he may declare it, for why is the land perished and is burned up like a wilderness, that none passes through?

Hear you, and give ear; be not proud: for the LORD has spoken.

Why will you die, you and your people, by the sword, by the famine, and by the pestilence, as the LORD has spoken against the nation that will not serve the king of Babylon?

And the plunderer shall come upon every city, and no city shall escape: the valley also shall perish, and the plain shall be destroyed, as the LORD has spoken.
