The first two articles address the legislative and executive branches of government. Article III of the United States Constitution is devoted to the Judicial Branch. Section one of the third article helps to establish the language which constructs the Supreme Court:
The judicial power of the United States, shall be vested in one Supreme Court, and in such inferior courts as the Congress may from time to time ordain and establish.

It is in the first section of the article where the language enabling it to exist becomes evident. For the framers of the Constitution, it becomes essential that the first section of the article to clearly establish the language that creates the Supreme Court.
