According to Christian understanding, the author Daniel wrote about wise men speaking to King Nebuchadnezzar. They asked the king to tell them his dream so they could explain what it meant.
Daniel 2:4: Then spake the Chaldeans to the king in Syriack, O king, live for ever: tell thy servants the dream, and we will shew the interpretation. [O king...: (Chaldee, to the end of chapter seven]
Daniel 2:4 marks a transition in the Book of Daniel from Hebrew to Aramaic, which lasts until Daniel 7:28. This has raised questions about why different languages are used in different parts of the book, leading to debates about the book's unity and origin. Some scholars see this as evidence of composite authorship or later editing.
