'Group' in the Bible

When the king spoke with them, he did not find among the entire group anyone like Daniel, Hananiah, Mishael, or Azariah. So they entered the king's service.

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."
