'Hereby' in the Bible

I hereby decree that any people, nation, or language group that blasphemes the god of Shadrach, Meshach, or Abednego will be dismembered and his home reduced to rubble! For there exists no other god who can deliver in this way."

While these words were still on the king's lips, a voice came down from heaven: "It is hereby announced to you, King Nebuchadnezzar, that your kingdom has been removed from you!

"I hereby decree that in every area of my kingdom men are to fear and tremble before the God of Daniel. For he is the living God, who endures forever. His kingdom is one that will not be destroyed, and his dominion continues forever.
